Abstract:
ABSTRACTDiscovery of superconductivity in BiS2 layers based systems has attracted tremendous interest of both experimentalists and theoreticians from condensed matter physics community. In this article, a review of our high pressure studies on BiS2 based superconductors is given. The pressure effects on magnetic, transport properties and superconducting transitions are discussed for different types of doped and undoped BiS2-based compounds such as Bi4O4S3 and ReO/FBiS2 (Re = rare-earth). Pressure tends to decrease the magnetic transition temperature in the undoped or only slightly doped compounds. The superconducting Tc increases with low pressure for under doped BiS2 based compounds, remains approximately constant for optimal doping, and decreases linearly in the overdoped range. Under pressure, the semiconducting behavior in the normal state is suppressed markedly and monotonically, whereas the evolution of Tc is nonlinear, the superconductivity in the BiS2 layer favors the Fermi surface at the boundary between the semiconducting and metallic behaviors. However, strong suppression of the semiconducting and induced metallic behavior without doping in ReO/FBiS2 suggests that the Fermi surface is located in the vicinity of some instability. Furthermore, notable properties under pressure in the BiS2 family are reported. The prospects for raising Tc in this family are proposed on the basis of experimental and theoretical studies.

Abstract:
Since 2012, layered compounds containing Bi-Ch (Ch: S and Se) layers have been extensively studied in the field of superconductivity. The most-studied system is BiS2-based superconductors with two-layer-type conducting layers. Recently, superconductivity was observed in La2O2M2S6 (M = metals), which contains four-layer-type conducting layers. The four-layer-type Bi-based superconductors are new systems in the family of Bi-based superconductors; we can expect further development of Bi-based layered superconductors. In this review article, we summarize the progress of synthesis, structural analysis, investigations on superconducting properties, and material design of the four-layer-type Bi-based superconductors. In-plane chemical pressure is the factor essential for the emergence of bulk superconductivity in the system. The highest Tc of 4.1 K was observed in Rare Earth elements (RE) substituted La2-xRExO2Bi3Ag0.6Sn0.4S6.

Abstract:
We have investigated the local structure of BiS2-based layered materials by Bi L3-edge extended X-ray absorption fine structure (EXAFS) measurements performed on single crystal samples with polarization of the X-ray beam parallel to the BiS2 plane. The results confirm highly instable nature of BiS2 layer, characterized by ferroelectric like distortions. The distortion amplitude, determined by the separation between the two in-plane (Bi-S1) bonds, is found to be highest in LaO0.77F0.23BiS2 with ΔR∼0.26 Å and lowest in NdO0.71F0.29BiS2 with ΔR∼0.13 Å. Among the systems with intrinsic doping, CeOBiS2 shows smaller distortion (ΔR∼0.15 Å) than PrOBiS2 (ΔR∼0.18 Å) while the highest distortion appears for EuFBiS2 revealing ΔR∼0.22 Å. It appears that the distortion amplitude is controlled by the nature of the RE(O,F) spacer layer in the RE(O,F)BiS2 structure. The X-ray absorption near edge structure (XANES) spectra, probing the local geometry, shows a spectral weight transfer that evolves systematically with the distortion amplitude in the BiS2-layer. The results provide a quantitative measurements of the local distortions in the instable BiS2-layer with direct implication on the physical properties of these materials.

Abstract:
The Canadian Conservation Institute (CCI) has developed a Geographic Information System (GIS) of hazards for Canadian cultural heritage institutions. The greatly increased access to open data is changing how advisory bodies like the CCI and the public can access and share information. For the purpose of investigating how a GIS approach can assist the CCI with its mandate to improve the preservation of collections, a map layer of cultural heritage institutions across Canada has been assembled and continues to be upgraded for accuracy, inclusion and detail (Fig. 1). This was combined with a collation of hazard layers; a partial list includes: seismic risk, notably expectations of earthquake severity tied to improvements in the national building code, tsunami exposure, wildfire data, hurricane, tornado, lightning density, pest distribution, and energy use indicators such as heating degree days and climate norm data. The platform allows examination of expectations around climate change driven risks such as sea-level rise, storm-incursions, permafrost melt. The GIS approach will also allow reassessments around expected changes to flood risk maps issued by jurisdictions, as well as Statistics Canada layers on population related factors such as changes in numbers of local populations, income and demographic shifts which can be stressors or opportunities. Sources have been drawn from federal, provincial, municipal, and academic evaluations of hazards, which now are more commonly published as GIS products. Mapping Canadian heritage institution's within a GIS improves our ability to: visualise and interpret to clients the relative magnitude of their local hazards, make ties to more refined local analyses, and show adjacencies to mapped historical events. From a national perspective the GIS can generate profiles of aggregated institutional exposure to the hazards, and more readily identify sub-populations of institutions for which particular risks would rank higher or lower among their concerns. This improves CCI's preventive conservation advisory service's perspective on mappable risks for any institution we deal with as clients. Ultimately, through federal initiatives in open data, it is our intention that client groups can look at the GIS for the purpose of educating themselves on hazards they would want to prepare for.

The EL spectrum peak is at 430 nm, indicating that the carrier recombination is confined in the NPB layer, in additional light emission originates from NPB. Compared with the luminous efficiency of the conventional diode without CuPc layer, that of the diode with HCL has been sharply increased up to 2.62 cd /A. It suggested that the CuPc and BCP exactly function as hole-consuming and hole-blocking layers, respectively, which enhance the efficiency of carrier，s recombination and confine the excitation in the EL layer.

Abstract:
In the present paper we demonstrate and compare different properties of Bi and Bi1-xSbx thin films placed on polyimide (PI) substrate in frequency range from 0.2 to 1.0 THz. Bi films with a thickness of 40, 105 and 150 nm have been studied as well as 150 nm Bi1-xSbx solid solutions with Sb concentration of 5, 8, 12 and 15 %. An effective refractive index and permittivity of whole substrate/film structures have been derived by using terahertz time-domain spectroscopy (THz-TDS) method. These measurements have shown the positive phase shift in PI substrate with a thickness of 42 μm and revealed that it is barely transparent in studied frequency range, but the whole substrate/film structure provides the negative phase shift of terahertz wave. It was shown that the permittivity depends on mobility of charge carriers which is driven by film thickness and antimony content.

Abstract:
The thermal atomic layer deposition (ALD) of copper oxide films from the non-fluorinated yet liquid precursor bis(tri-n-butylphosphane)copper(I)acetylacetonate, [(nBu3P)2Cu(acac)], and wet O2 on Ta, TaN, Ru and SiO2 substrates at temperatures of < 160°C is reported. Typical temperature-independent growth was observed at least up to 125°C with a growth-per-cycle of ~ 0.1 Å for the metallic substrates and an ALD window extending down to 100°C for Ru. On SiO2 and TaN the ALD window was observed between 110 and 125°C, with saturated growth shown on TaN still at 135°C. Precursor self-decomposition in a chemical vapor deposition mode led to bi-modal growth on Ta, resulting in the parallel formation of continuous films and isolated clusters. This effect was not observed on TaN up to about 130°C and neither on Ru or SiO2 for any processing temperature. The degree of nitridation of the tantalum nitride underlayers considerably influenced the film growth. With excellent adhesion of the ALD films on all substrates studied, the results are a promising basis for Cu seed layer ALD applicable to electrochemical Cu metallization in interconnects of ultralarge-scale integrated circuits. © 2009 The Electrochemical Society.

Es wird die thermische Atomlagenabscheidung (ALD) von Kupferoxidschichten, ausgehend von der unfluorierten, flüssigen Vorstufenverbindung Bis(tri-n-butylphosphan)kupfer(I)acetylacetonat, [(nBu3P)2Cu(acac)], sowie feuchtem Sauerstoff, auf Ta-, TaN-, Ru- und SiO2-Substraten bei Temperaturen < 160°C berichtet. Typisches temperaturunabhängiges Wachstum wurde zumindest bis 125°C beobachtet. Damit verbunden wurde für die metallischen Substrate ein Zyklenwachstum von ca. 0.1 Å erzielt sowie ein ALD-Fenster, das für Ru bis zu einer Temperatur von 100°C reicht. Auf SiO2 und TaN wurde das ALD-Fenster zwischen 110 und 125°C beobachtet, wobei auch bei 135°C noch gesättigtes Wachstum auf TaN gezeigt werden konnte. Die selbständige Zersetzung des Precursors ähnlich der chemischen Gasphasenabscheidung führte zu einem bimodalen Schichtwachstum auf Ta, wodurch gleichzeitig geschlossene Schichten und voneinander isolierte Cluster gebildet wurden. Dieser Effekt wurde auf TaN bis zu einer Temperatur von 130°C nicht beobachtet. Ebensowenig trat er im untersuchten Temperaturbereich auf Ru oder SiO2 auf. Der Nitrierungsgrad der TaN-Schichten beeinflusste hierbei das Schichtwachstum stark. Mit einer sehr guten Haftung der ALD-Schichten auf allen untersuchten Substratmaterialien erscheinen die Ergebnisse vielversprechend für die ALD von Kupferstartschichten, die für die elektrochemische Kupfermetallisierung in Leitbahnsystemen ultrahochintegrierter Schaltkreise anwendbar sind

Abstract:

As a possible alternative for growing seed layers required for electrochemical Cu deposition of metallization systems in ULSI circuits, the atomic layer deposition (ALD) of Cu is under consideration. To avoid drawbacks related to plasma-enhanced ALD (PEALD), thermal growth of Cu has been proposed by two-step processes forming copper oxide films by ALD which are subsequently reduced.

This talk, given at the 8th International Conference on Atomic Layer Deposition (ALD 2008), held in Bruges, Belgium from 29 June to 2 July 2008, summarizes the results of thermal ALD experiments from [(nBu3P)2Cu(acac)] precursor and wet O2. The precursor is of particular interest as it is a liquid at room temperature and thus easier to handle than frequently utilized solids such as Cu(acac)2, Cu(hfac)2 or Cu(thd)2. Furthermore the substance is non-fluorinated, which helps avoiding a major source of adhesion issues repeatedly observed in Cu CVD.

As result of the ALD experiments, we obtained composites of metallic and oxidized Cu on Ta and TaN, which was determined by angle-resolved XPS analyses. While smooth, adherent films were grown on TaN in an ALD window up to about 130°C, cluster-formation due to self-decomposition of the precursor was observed on Ta. We also recognized a considerable dependency of the growth on the degree of nitridation of the TaN. In contrast, smooth films could be grown up to 130°C on SiO2 and Ru, although in the latter case the ALD window only extends to about 120°C. To apply the ALD films as seed layers in subsequent electroplating processes, several reduction processes are under investigation. Thermal and plasma-assisted hydrogen treatments are studied, as well as thermal treatments in vapors of isopropanol, formic acid, and aldehydes. So far these attempts were most promising using formic acid at temperatures between 100 and 120°C, also offering the benefit of avoiding agglomeration of the very thin ALD films on Ta and TaN. In this respect, the process sequence shows potential for depositing ultra-thin, smooth Cu films at temperatures below 150°C.

This thesis concerns the organic modification for the Mg–Al layered double hydroxides (LDHs), more specifically, the intercalation profile of the clay with a series of poly(oxypropylene)-bis-amidoacids (POAs). A number of important issues are included in the thesis. (1)The intercalation of LDH by the POP-amidoacids and the spatial enlargement of the gallery up to 94 Å d spacing. (2)The critical intercalation of using the POP2000-2MA-2Na for expanding the LDH gallery. It provides a new way for manipulating nanomaterials and control of polymer conformations in the LDH confinement. (3)The amphiphilic property of POP2000-2MA-Na/LDH hybrid and their ability of lowering the toluene/water interfacial intension to 4.5 mN/m at the critical micelle concentration (CMC) of 0.01 wt%. (4)Newly discovered mechanisms that involving hydrogen-bonding and chelation. The different clays such as LDH, MMT and Mica are compared for the generality of the new mechanisms. (5)A pH dependence of the organo-LDH hybrids that particularly occurrence of layered structure collapse at low pH environment. The implication is an application of organic encapsulation and control release that could be developed for such a clay hybrid. In addition, the hybrids also possess thermal-sensitivity, that allows a fine dispersion at low temperature (5~10 oC) and aggregation at higher temperature (＞20 oC).

Thermoelectric devices can convert heat into electricity directly, and have attracted enormous research interests. There are usually numerous solder (or braze) joints in thermoelectric devices. To prevent direct contact and interfacial reactions between solder (or braze) and thermoelectric materials, barrier layer is often used. Ni is the most commonly used barrier layer material. Examination of the interfacial reactions between Ni and thermoelectric substrates is fundamentally important for reliability assessment of the thermoelectric devices. This study investigates interfacial reactions between Ni and three kinds of thermoelectric materials: Ag2Te, (Bi,Sb)2Te3, and Bi2(Te,Se)3. The thermoelectric substrates are prepared with proper amounts of pure constituent elements, and are then plated with Ni. The thickness of Ni layer is 60μm. Ni3Te2, NiTe0.775 and NiTe2 are formed in the Ni/Te couple reacted at 200oC for 720 hours. Two reaction regions are observed in the Ni/Ag2Te couple reacted at 200oC for 720 hours. A continuous Ag layer is formed adjacent to the Ni substrate. The other reaction region is a two-phase finger-type mixture. The darker phase in this two-phase region is the Ni3Te2 phase and the other brighter phase is Ag2Te phase with Ni solubility. This study also investigates the interfacial reactions between Ni/Te couple and Ag2Te couple at 250 oC. Ni3Te2, NiTe0.775 and NiTe2 are also formed in the Ni/Te couple reacted at 250oC for 720 hours, and the thickness of reaction layer is about 102.6μm. Two reaction regions are observed in the Ni/Ag2Te couple reacted at 250oC for 720 hours. A continuous Ag layer is formed adjacent to the Ni substrate. Comparing with those in the Ni/Ag2Te 200oC reaction couple, a continuous Ni3Te2 reaction layer is formed adjacent to the Ag2Te substrate. The interfacial reactions between the Ni barrier layer and the P-type (Bi1-xSbx)2Te3 and n-type Bi2(Te1-ySey)3 thermoelectric materials at 300oC are examined. Two reaction phase layers are observed in the Ni/(Bi0.25Sb0.75)2Te3 couples reacted at 300oC. The phase layer adjacent to the Ni substrate is likely a Sb-Ni-Te ternary compound or the Ni3Te2 phase with significant Sb solubility.In the In the Ni/ Bi2(Te0.9Se0.1)3 couple reacted at 300oC two reaction phase layers are also found. The BiTe phase is adjacent to the Bi2(Te0.9Se0.1) substrate, while a Bi-Ni-Te ternary compound or the NiTe2 phase with Bi solubility is formed adjacent to the Ni substrate. It can be found that the thickness of the reaction layers in the Ni/Bi2(Te0.9Se0.1)3 couple is thicker than that in the Ni/(Bi0.25Sb0.75)2Te3. Furthermore, the reaction rate at 300oC is faster than that at 250oC.

Abstract:
Since the discovery of superconductivity in a high-entropy alloy (HEA) Ti-Zr-Nb-Hf-Ta in 2014, the community of superconductor science has explored new HEA superconductors to find the merit of the HEA states on superconducting properties. Since 2018, we have developed “HEA-type” compounds as superconductors or thermoelectric materials. As well known, compounds like intermetallic compounds or layered compounds are composed of multi crystallographic sites. In a HEA-type compounds, one or more sites are alloyed and total mixing entropy satisfies with the criterion of HEA. Herein, we summarize the synthesis methods, the crystal structural variation and superconducting properties of the HEA-type compounds, which include NaCl-type metal tellurides, CuAl2-type transition metal zirconides, high-Tc cuprates, and BiS2-based layered superconductors. The effects of the introduction of a HEA site in various kinds of complicated compounds are discussed from the structural-dimensionality viewpoint.

Full text
Abstract:
Substitutionally inert ruthenium complexes bearing benzimidazole derivatives have unique electrochemical and photochemical properties. In particular, proton coupled electron transfer (PCET) in ruthenium–benzimidazole complexes leads to rich redox chemistry, which allows e.g. the tuning of redox potentials or switching by deprotonation. Using the background knowledge from acquired from their solution-state chemistry, Ru complexes immobilized on electrode surfaces have been developed and these offer new research directions toward functional molecular devices. The integration of surface-immobilized redox-active Ru complexes with multilayer assemblies via the layer-by-layer (LbL) metal coordination method on ITO electrodes provides new types of functionality. To control the molecular orientation of the complexes on the ITO surface, free-standing tetrapodal phosphonic acid anchor groups were incorporated into tridentate 2,6-bis(benzimidazole-2-yl)pyridine or benzene ligands. The use of the LbL layer growth method also enables “coordination programming” to fabricate multilayered films, as a variety of Ru complexes with different redox potentials and pKa values are available for incorporation into homo- and heterolayer films. Based on this strategy, many functional devices, such as scalable redox capacitors for energy storage, photo-responsive memory devices, proton rocking-chair-type redox capacitors, and protonic memristor devices have been successfully fabricated. Further applications of anchored Ru complexes in photoredox catalysis and dye-sensitized solar cells may be possible. Therefore, surface-confined Ru complexes exhibit great potential to contribute to the development of advanced functional molecular devices.

Abstract:
The need for light weight, low power multicolor displays and backlights has spurred interest in thin-film, organic electroluminescent (EL) devices. A typical organic EL device consists of an indium-tin oxide anode (ITO) layer on a glass substrate, and sequential layers of bis(triphenyl)diamine (TAD, hole transporter), tris(8-hydroxyquinoline)aluminum (A1Q, electron transporter and green light-emitter), and a low work function metal cathode (e.g., Al or Mg:Ag).1 Device efficiency, stability, and spectral output can be tailored by incorporating intermediate layers of organic hole-blockers2 or blue-emitters,3 or doping A1Q with narrow spectral linewidth organic dyes.4 Cavity resonance effects have been employed in lithographically patterned optical microcavities to select single5or multiple6 colors out of broad spectrum organic emitters like A1Q. Device efficiency is a critical parameter, especially for liquid crystal display backlight applications. We will describe an approach for white light EL and an approach for enhancing device efficiency.

Abstract:
For several years we have been developing polyimide-based electro-optic materials based on commercially available components. In 1992, we described a proof-of-principle all-polyimide triple stack Mach-Zehnder modulator using DCM (4-(dicyanomethylene)-2-methyl-6-(p-di-methylaminostyryl)-4H-pyran) in Amoco Ultradei 3112 polyimide as the active core layer with Amoco Ultradei 4212 polyimide cladding layers.1 During the course of our work we found that some commercial preparations of DCM contained a significant amount of a less soluble, more thermally stable impurity which we identified as the bis condensation product arising from the synthesis of DCM itself.2 This impurity, DAD, and several analogs were synthesized, and their physical and NLO properties were investigated.3 Figure 1 shows the synthetic scheme used for their preparation.

Abstract:
Abstract This paper presents recent research into the effects of etching treatments on the interface strength between nickel titanium (NiTi) fibers and a bismuth tin (BiSn) matrix composing a self-healing metal-metal composite. Self-healing metallic composites have the potential to create a paradigm shift in the design of engineered structures by changing what is considered a “failure,” resulting in lighter weight and safer structures with reduced maintenance requirements. Some of the most advanced self-healing metal-metal composites are composed of NiTi shape memory alloy fibers reinforcing an off-eutectic metal matrix. When activated these materials can recover from macroscopic deformations and matrix fracture, returning to their original geometry and then soldering cracks closed. This process restores nearly 100% of original strength without using any consumable adhesives. As a result, this healing process has the potential to be repeated indefinitely. The strength of the interface between the fibers and matrix is critical to creating high-quality composites because it governs the ability to transfer loads between the matrix and fibers, through the structure. Unfortunately, NiTi forms an inert native titanium oxide (TiO2) surface layer when exposed to air that is notoriously hard to bond to. To overcome this weak bonding most initial work in self-healing using NiTi fibers employed structural anchors within specimens for the NiTi to react against. This approach was functional for demonstrating basic components of self-healing abilities but negated distributed load transfer between the fibers and matrix of the composite structure, creating concentrated load-paths and resulting in a poor composite structure. Chemical etching in an inert environment has been performed to remove the inert TiO2 surface layer from NiTi, but the resulting interface strength has not previously been quantified. This paper presents an experimental investigation of the strength of the interface between NiTi and BiSn with both the native oxide layer present (control) and after undergoing a chemical etching process in an inert environment to remove the TiO2 layer and coating the NiTi while in the inert environment to prevent re-formation of the TiO2 layer. Testing was performed using single fibers of NiTi cast into and extending out of a BiSn block. The fiber/wire was mechanically pulled out of the BiSn block while measuring the force applied and recording video of the process. The experimental evaluation of these interface strengths in this research will enable the efficient design of composite materials to ensure proper load transfer between composite fibers and matrix to maximize strength and support self-healing capabilities.

Abstract:
We use AI techniques to statistically rigorously analyze combinations of query responses of two personality-related questionnaires. One questionnaire probes aspects of a participant’s character (SOI) and the other avoidance of aversive outcomes together with approaches to goal orientated outcomes (BIS/BAS). We use one-hot encoding, dimension reduction with a neural network (a seven-layer auto-encoder) and two clustering algorithms to detect associations between the twelve combinations of SOI and BIS/BAS groups. We discover that for most combinations more than one association exists. Traditional, fallacious statistical methods cannot find these outcomes.

Abstract:
It has recently been shown that ordered, organic thin films of planar stacking molecules can be grown with monolayer uniformity and control over large substrate distances by the ultrahigh vacuum process of organic molecular beam deposition (OMBD). Due to this ability to grow films with such a high degree of order, it was demonstrated by So, et al1 , 2 that multiple quantum well stacks consisting of alternating layers of the archetype compounds, 3,4,9,10 perylenetetracarboxylic dianhydridc (PTCDA) and 3,4,7,8 naphthalenetetracarboxylic dianhydride (NTCDA) exhibit exciton quantum confinement That is, energy shifts in the absorption spectrum, as well as time resolved photolumincscence indicates systematic changes with layer thickness, as the thickness is reduced from 500Å to 10Å. While these early data were compelling, they opened up many questions as to the nature of excitons in closely packed organic molecular systems. Hence, in this work, we have extended this early investigation by measuring the electroabsorption, the absorption and the fluorescence spectra of organic MQW stacks consisting of PTCDA+NTCDA, as well as 3,4,9,10 peryleneietracarboxylic-bis-benzimidazole (PTCBI)+NTCDA. These new investigations provide further information essential to understanding the nature of excitons in these van der Waals-bonded molecular solids.

Abstract:
In this study, the tribological behavior of the Trihexyl tetradecylphosphonium-bis(2,4,4-trimethylpentyl)phosphinate [THTDP][Phos] ionic liquid with and without single-wall carbon nanotubes (SWCNT) dispersion as a thin boundary layer was intended for investigation. However, the surface heat treatment process was not sufficient to form a thin film on the sample surfaces. Thus, in each test condition, the lubricating agents were used as external (liquid) lubricants. Specifically, [THTDP][Phos] and ([THTDP][Phos]+0.1 wt.% SWCNT) boundary film layers were applied on 6061-T6 aluminum alloy disk samples and tested under sliding contact with 1.5 mm diameter 420C stainless steel balls using a ball-on-flat linearly reciprocating tribometer. A commercially available Mobil Super 10W-40 engine oil (MS10W40) was also tested and used as this investigation’s datum. The tribological behavior of [THTDP][Phos] and ([THTDP][Phos]+SWCNT) boundary film layers was analyzed via wear volume calculations from optical microscopy measurements, as well as by observation of the transient coefficient of friction (COF) obtained through strain gauge measurements made directly from the reciprocating member of the tribometer. Results indicate the potential for reduction of wear volume and coefficient of friction in the IL lubricated steel-on-aluminum sliding contact through (SWCNT) dispersion in the ionic liquid. Wear results are based on measurements obtained using optical microscopy (OM). Results discussed display improved tribological performance for both [THTDP][Phos] and ([THTDP][Phos]+SWCNT) over baseline MS10W40 oil lubricant for both roughness values tested for the steel-on-aluminum contact. No measurable improvements were observed between [THTDP][Phos] and ([THTDP][Phos]+SWCNT) tests.
