Streszczenie:

Quantum-dot Cellular Automata (QCA) is a new emerging technology for designing electronic circuits in nanoscale. QCA technology comes to overcome the CMOS limitation and to be a good alternative as it can work in ultra-high-speed. QCA brought researchers attention due to many features such as low power consumption, small feature size in addition to high frequency. Designing circuits in QCA technology with minimum costs such as cells count and the area is very important. This paper presents novel structures of D-latch and D-Flip Flop with the lower area and cell count. The proposed Flip-Flop has SET and RESET ability. The proposed latch and Flip-Flop have lower complexity compared with counterparts in terms of cell counts by 32% and 26% respectively. The proposed circuits are designed and simulated in QCADesigner software.

We have developed a novel atomic force microscope (AFM) probe as a highly sensitive sensor and an application of the probe into various mechanical tests for characterizing micro/nanostructures. Using MEMS fabrication technique, we have designed and fabricated rhombus-shaped symmetric AFM probe. Adhesion forces between silicon tip and artificial nano-hair structures of cyclic olefin copolymer (COC) and polypropylene (PP) were measured using the probe with a flat tip. The results exhibited the usual characteristics of force-displacement curves of COC and PP nano-hair structures, in which a pull-off force was detected at the point of unloading. The average adhesion forces of the COC and PP hair structures are about 9.48 μN and 10.67 μN, respectively.

The present study has a dual aim of supporting magnetic nanoparticles over the nanolayers of LDHs and designing two-dimensional magnetic nano-nets of cobalt ferrite. In this trend, nanoparticles of CoFe2O4 were prepared and supported by Co-Fe LDH through urea hydrolysis. The nanolayered structures of Co-Fe LDH were confirmed by X-ray diffraction, energy-dispersive X-ray spectrometry, FT-IR spectra, thermal analyses, and transmission electron microscopy. In addition, they indicated that 13.2% CoFe2O4 were supported over Co-Fe LDH. Transformation of the nanolayered structures of Co-Fe LDH to nano-nets was achieved by the catalytic effect of the supported CoFe2O4 nanoparticles through solvent thermal technique. X-ray diffraction patterns and transmission electron microscopy images confirmed the transformation of the supported Co-Fe LDH to nano-nets of cobalt ferrite. In order to indicate the effect of the LDH for designing the nano-nets, nanoparticles of cobalt ferrite were prepared by the same technique without LDH. The magnetic behavior of the nano-nets and the supported Co-Fe LDH were measured and compared with the nanoparticles through vibrating sample magnetometer technique. The magnetic parameters indicated that the prepared nano-nets have ferromagnetic behavior and high coercivity. However, the prepared nanoparticles revealed a superparamagnetic state and low coercivity. The experimental results concluded that the incorporation of nanoparticles with nanowires into nano-net structures has been found to be an efficient way to improve their magnetic properties and prevent their agglomerations. Finally, layered double hydroxides are an important source for constructing magnetic nanolayered structures and nano-nets.

AbstractThis paper considers nonlinear interactions between vibration modes with a focus on recent studies relevant to micro- and nanoscale mechanical resonators. Due to their inherently small damping and high susceptibility to nonlinearity, these devices have brought to light new phenomena and offer the potential for novel applications. Nonlinear interactions between vibration modes are well known to have the potential for generating a “zoo” of complicated bifurcation patterns and a wide variety of dynamic behaviors, including chaos. Here, we focus on more regular, robust, and predictable aspects of their dynamics, since these are most relevant to applications. The investigation is based on relatively simple two-mode models that are able to capture and predict a wide range of transient and sustained dynamical behaviors. The paper emphasizes modeling and analysis that has been done in support of recent experimental investigations and describes in full detail the analysis and attendant insights obtained from the models that are briefly described in the experimental papers. Standard analytical tools are employed, but the questions posed and the conclusions drawn are novel, as motivated by observations from experiments. The paper considers transient dynamics, response to harmonic forcing, and self-excited systems and describes phenomena such as extended coherence time during transient decay, zero dispersion response, and nonlinear frequency veering. The paper closes with some suggested directions for future studies in this area.

Streszczenie:

Controlling the morphology and composition of semiconductor nano- and micro-structures is crucial for fundamental studies and applications. Here, Si-Ge semiconductor nanostructures were fabricated using photolithographically defined micro-crucibles on Si substrates. Interestingly, the nanostructure morphology and composition of these structures are strongly dependent on the size of the liquid–vapour interface (i.e., the opening of the micro-crucible) in the CVD deposition step of Ge. In particular, Ge crystallites nucleate in micro-crucibles with larger opening sizes (3.74–4.73 μm2), while no such crystallites are found in micro-crucibles with smaller openings of 1.15 μm2. This interface area tuning also results in the formation of unique semiconductor nanostructures: lateral nano-trees (for smaller openings) and nano-rods (for larger openings). Further TEM imaging reveals that these nanostructures have an epitaxial relationship with the underlying Si substrate. This geometrical dependence on the micro-scale vapour–liquid–solid (VLS) nucleation and growth is explained within a dedicated model, where the incubation time for the VLS Ge nucleation is inversely proportional to the opening size. The geometric effect on the VLS nucleation can be used for the fine tuning of the morphology and composition of different lateral nano- and micro-structures by simply changing the area of the liquid–vapour interface.

Streszczenie:

In this work, the use of theoretical tools of molecular modeling for tailoring 1D novel nanomaterials is demonstrated. There are four selected nano-structures as examples, each tailored for a specic demand of nano-technology that is yet to be fullled. For the purpose of modeling/calculating the electronic and structural properties, various methods of dening the interatomic interaction, such as empirical potential energy functions, semi-empirical methods and density functional theory, are used. Each of these methods have a dierent level of approximations leading to limitations in their use. Furthermore, each method needs to be calibrated carefully in order to obtain physically meaningful results. Examples being novel nano-structures, there does not exist any experimental observations directly studying the material at hand. Thus, in order to obtain a parameter set that best describes the system, a series of pre-existing structures that are physically and/or chemically related are used. Among the methods employed, the density functional theory (DFT) is certainly the most popular one, due to its accuracy and more importantly the framework it provides for perturbative extensions otherwise nearly impossible to calculate in Hartree-Fock level.

Streszczenie:

Patterning, the utilisation and manipulation of geometric properties, is important both for the rational design of technological devices and also to the understanding of many natural phenomena. In this thesis I examine the way in which micro and nano patterning can alter optical properties across a large range of wavelength scales and how these novel phenomena can be utilised. Micro patterned electrodes can tune the geometry of radio frequency electric fields to generate dielectrophoretic microfluidic devices. These devices use the dielectrophoretic force to sort, position and characterise the properties of micro and nano particles. I develop a new image processing algorithm that radically improves experimental efficiency allowing for real-time supervisor free dielectrophoretic characterisation of nanoparticles. Metamaterials are composite structures that have repeating units that are much smaller than the wavelength of radiation they are designed to work with. The optical properties of the materials are derived from these units rather than the bulk characteristics of the materials they are composed of. I demonstrate the development of novel THz metamaterial absorber devices. These devices provide a means to design and control the absorption of THz radiation, modulating bandwidth, polarization dependence and frequency in a form that is readily integrable with other standard fabrication processes. Finally by periodically patterning materials on the nanometer scale I demonstrate the development of novel photonic crystal devices and complementary optical components. In these devices the periodicity of the electromagnetic wave is modulated by the periodicity of the structures themselves resulting in band gaps and resonances analogous to the band gaps and defect states found commonly in semi-conductor physics. I demonstrate the theory, fabrication and measurement of these devices using novel broadband supercontinuum sources and propose a future application for biosensing. Further topics covered in the appendix include the development of a spin out technology, a $100 open source atomic force microscope developed while spending time in China. Finally I examine the role of patterning for optimising the performance of nanomechanical cantilever biosensors, and show how geometrical effects on the microscopic scale are crucial to understanding the workings of the vancomycin family of antibiotics, as screened using microcantilevers. Portions of this report are edited extracts from published articles resulting from this work, a full list of which is given in Appendix A.

Solution chemistry is a versatile and powerful tool in the synthesis of designed, complex nano-level high-tech materials. Normally, the technique is considered too expensive for large-scale production of complex multi-component ceramic materials. This thesis describes the expansion of the useful area of solution processing to multi-component bulk materials such as ZnO-based high-field varistors and WC–Co cutting tools, by developing novel techniques for solution-based coating of conventionally prepared metal and ceramic powders. The chemistry and microstructure development in the preparation of coatings, and the sintering of the coated powders to compacts, were studied in detail by SEM-EDS, TEM-EDS, XRD, IR-spectroscopy, dilatometry, TGA and DSC chemical analysis.

ZnO powder with a ca 20 nm thick, homogeneous oxide coat of Bi–Sb–Ni–Co–Mn–Cr–Al oxide was prepared. After sintering to dense varistor bodies, much improved microstructures with much reduced ZnO-grain sizes were obtained. This shows that the oxides added as liquid sintering aid and grain-growth inhibitor become much more active when added homogeneously as a skin on the ZnO powder.

After sintering of cobalt-coated WC, much improved micro-structures were obtained with a much more narrow WC grain-size distribution than that obtained from starting powders mixed by a conventional milling route. Coated powders also obviate the need for the extensive milling of WC and Co powders used in conventional mixing.

The novel solution route was also applied to preparation of porous sponges and thin films on metal, glass and Al₂O₃ of sub 20 nm sized Co- or Ni-particles.

Streszczenie:

This thesis addresses novel nanocomposite materials by incorporating quantum dots, and other nanoentities, into polymer and sol-gel derived matrices, aiming to produce integrated photonic structures. Its objectives embrace the synthesis and the investigation of photonic materials, together with alternative fabrication methodologies enabling the effective integration of functional nanocomposite photonic structures, such as active waveguides, micro-ring structures and diffractive optical elements for sensing applications. Design, synthesis and characterization of nanocomposite materials in this context, involves QD incorporation in tailored-made polymers, synthesized using radical polymerization as well as QD embedment in titania matrices synthesized via sol-gel methods. Low cost sol-gel derived silica incorporating NiCl2 ¬ nanoentities was exploited in the proposed scheme of remote point sensing for ammonia detection. Commercially available hybrid organic/inorganic materials of the ORMOCER family are also used for structure fabrication. Further to microscopy, characterization of the materials mainly includes spectroscopic studies and refractive index measurements using reflectance interferometry. For the demonstration of complex photonic structures by using nanocomposites elaborated studies are presented here focusing on two fabrication methods: a) direct laser ablative microfabrication using ArF excimer radiation at λ=193 nm and, b) soft lithography. To achieve this, a fully automated ArF excimer laser microfabrication station was established comprising computer controlled nanopositioning and laser beam control, as well as various prototype materials synthesis and fabrication devices. QD/polymer computer generated holograms, waveguides and micro-ring structures were simulated, designed and fabricated. Specific protocols and method were established. A modified solvent-assisted soft lithography method was also used for micropatterning and fabrication of photonic structures using QD/polymer and QD/titania films in conjunction to common UV and thermally curable materials. A solvent vapor smoothing process was found to significantly enhance the quality of the structures as observed with scanning electron microscopy. QD/polymer computer generated holograms, diffractive optical elements, micro-ring structures, vertical cavity resonators and other advanced photonic structures comprising quantum dot nanocrystals and nano-entities are investigated. A new photonic sensing scheme is proposed and demonstrated here for remote, spatially-localized sensing. It comprises a low cost diffractive thin film of a sensing material remotely interrogated by use of light beams. A silica/NiCl2 system fabricated via the sol-gel methods and micropatterned using the direct laser ablative microfabrication method is demonstrated, to allow detection of as low as 1 ppm of ammonia. Finally, the merits of incorporating epitaxially grown quantum dots in highly resonant structures for signal amplification, namely vertical cavity semiconductor optical amplifier and micro-ring semiconductor optical amplifiers, are discussed. Such devices are demonstrated to lack a laser threshold if designed properly allowing for the full exploitation of the fast carrier dynamics of quantum dots by driving them at high currents, for amplification of high-bit-rate signals of up to 100 Gb/s. A rate equation theoretical model was developed which provides both performance prediction of the devices under discussion and design guidelines for threshold-less operation. This doctoral thesis served, as a whole, its main scope of providing a palette of materials and methods as well as some useful concepts for the fabrication of functional photonic structures and devices based on advanced nanocomposites.
Στην παρούσα διδακτορική διατριβή μελετώνται νανοδομημένα υλικά με ενσωματωμένες κβαντικές ψηφίδες και άλλες νανο-οντότητες σε πολυμερή και ανόργανες μήτρες μέσω της μεθόδου sol-gel, στοχευοντας στην κατασκευή δομών ολοκληρωμένων φωτονικών κυκλωμάτων. Οι στόχοι της διατριβής επικεντρώνονται στην σύνθεση και μελέτη φωτονικών υλικών και στον συνδυασμό τους με εναλλακτικές μεθόδους κατασκευής φωτονικών δομών. Τα νανοσύνθετα υλικά που μελετήθηκαν παρουσιάζουν μια σειρά από φωτονικές ιδιότητες για την υλοποίηση φωτονικών δομών διαφόρων λειτουργικοτήτων όπως ενεργοί οπτικοί κυματοδηγοί, ενεργοί συντονιστές μικροδακτυλίου και περιθλαστικά οπτικά στοιχεία για φωτονικές εφαρμογές. Στα πλαίσια της σχεδίασης, σύνθεσης και χαρακτηρισμού αυτών των νανοδομημένων υλικών κβαντικές ψηφίδες ενσωματώθηκαν σε πολυμερικές μήτρες ειδικά σχεδιασμένες για τον σκοπό αυτό καθώς και σε ανόργανες μήτρες παρασκευασμένων με την μέθοδο sol-gel. Μελετήθηκαν ακόμα υλικά διοξειδίου του πυριτίου εμπλουτισμένα με νανο-οντότητες χλωριούχου νικελίου του για χρήση σε φωτονικούς αισθητήρες. Τα υλικά αυτά συνετέθησαν με μεθόδους χαμηλού κόστους και χρησιμοποιήθηκαν σε καινοτόμες διατάξεις φωτονικών αισθητήρων που περιγράφονται εδώ. Επιπλέον μελετήθηκαν υβριδικά οργανικά/ανόργανα υλικά ORMOCER για την κατασκευή μιας σειράς φωτονικών διατάξεων. Ο χαρακτηρισμός των υλικών που περιγράφονται εδώ πραγματοποιήθηκε με φασματοσκοπικές μεθόδους ενώ ο δείκτης διάθλασης τους μετρήθηκε με την τεχνική της ανακλαστικής συμβολομετρίας. Η κατασκευή και επίδειξη σύνθετων νανοδομημένων φωτονικών διατάξεων πραγματοποιήθηκε με δύο μεθόδους: α) την μέθοδο φωτο-εκρηκτικής αποδόμησης με χρήση excimer laser σε μήκος κύματος λ=193 nm και β) με την μέθοδο soft lithography. Για τον σκοπό αυτό αναπτύχθηκε μια πλήρως αυτοματοποιημένη διάταξη μικροκατασκευής με χρήση ArF excimer laser στην οποία τόσο η πηγή laser όσο και η νανομετρική πλατφόρμα για την κίνηση του υπό διαμόρφωση δείγματος ελέγχονται από υπολογιστή. Η διάταξη αυτή χρησιμοποιήθηκε για την κατασκευή διαφόρων διατάξεων σε πολυμερικά υμένια με ενσωματωμένες κβαντικές ψηφίδες όπως υπολογιστικά σχεδιασμένων ολογραμμάτων, κυματοδηγοί και συντονιστές μικροδακτυλίου με γεωμετρικά χαρακτηριστικά που προκύπτουν από θεωρητικές προσομοιώσεις. Ακόμα αναπτύχθηκε μια παραλλαγή της μεθόδου soft lithography για την υποβοηθούμενη από χημικό διαλύτη φωτονικών δομών πολυμερικών μητρών και μητρών τιτανίας με ενσωματωμένες κβαντικές ψηφίδες σε συνδυασμό με κοινά υλικά σχεδιασμένα για την μέθοδο soft lithography και τα οποία διαμορφώνονται με έκθεση σε υπεριώδη ακτινοβολία. Στην διατριβή αυτή παρουσιάζεται ακόμα μια καινοτόμα σχεδίαση φωτονικών αισθητήρων για την τοπική ανίχνευση διαφόρων χημικών ή φυσικών παραγόντων από απόσταση. Οι αισθητήρες αυτοί αποτελούνται από περιθλαστικές δομές κατασκευασμένες σε υμένα κατάλληλων υλικών, οι οπτικές ιδιότητες των οποίων ανιχνεύονται με τη χρήση δέσμης laser. Ένας τέτοιος περιθλαστικός αισθητήρας αμμωνίας υμενίου διοξειδίου του πυριτίου με ενσωματωμένες νανο-οντότητες χλωριούχου νικελίου παρουσιάζεται εδώ, του οποίου η περιθλαστική δομή κατασκευάστηκε με τη μέθοδο της φωτο-εκρηκτικής αποδόμησης με laser. Ο αισθητήρας αυτός παρουσιάζει εξαιρετική επίδοση και ικανότητα ανίχνευσης αμμωνίας συγκέντρωσης μόλις 1 ppm. Τέλος, συζητούνται τα πλεονεκτήματα της χρήσης κβαντικών ψηφίδων αναπτυγμένων με την επιταξιακές μεθόδους σε δομές οπτικών ενισχυτών ισχυρού συντονισμού, συγκεκριμένα σε οπτικούς ενισχυτές ημιαγωγού κάθετης κοιλότητας και οπτικούς ενισχυτές ημιαγωγού μικροδακτυλίου. Συγκεκριμένα, επιδεικνύεται με τη χρήση ενός θεωρητικού μοντέλου που αναπτύχθηκε εδώ πως με τον κατάλληλο σχεδιασμό είναι δυνατόν στις διατάξεις αυτές να αποτρέπεται πλήρως η λειτουργία laser με την απουσία ρεύματος κατωφλίου. Η ιδιαιτερότητα αυτή επιτρέπει την χρήση μεγάλων ρευμάτων και την συνεπακόλουθη εκμετάλλευση της γρήγορης δυναμικής των φορέων στις κβαντικές ψηφίδες για την αποτελεσματική ενίσχυση σημάτων υψηλών ταχυτήτων (μεχρι 100 Gb/s). Η Διαδακτορική διατριβη, υπηρετεί συνολικά τον κύριο σκοπό της προσφέροντας μια παλέττα υλικών και μεθόδων για την ανάπτυξη λειτουργικών φωτονικών δομών και διατάξεων βασισμένων σε προηγμένα νανοσύνθετα υλικά.

Streszczenie:

Silicon based 3D fin structure is believed to be the potential future of current semiconductor technology. However, there are significant challenges still exist in realizing a manufacturable fin based process. In this work, we have studied the effects of hydrogen anneal on the structural and electrical characteristics of silicon fin based devices: tri-gate, finFET to name a few. H₂ anneal is shown to play a major role in structural integrity and manufacturability of 3D fin structure which is the most critical feature for these types of devices. Both the temperature and the pressure of H₂ anneal can result in significant alteration of fin height and shape as well as electrical characteristics. Optimum H₂ anneal is required in order to improve carrier mobility and device reliability as shown in this work. A new hard-mask based process was developed to retain H₂ anneal related benefit while eliminating detrimental effects such as reduction of device drive current due to fin height reduction. We have also demonstrated a novel 1T-1C pseudo Static Random Access Memory (1T-1C pseudo SRAM) memory cell using low cost conventional tri-gate process by utilizing selective H₂ anneal and other clever process techniques. TCAD-based simulation was also provided to show its competitive advantage over other types of static and dynamic memories in 45nm and beyond technologies. A high gain bipolar based on silicon fin process flow was proposed for the first time that can be used in BiCMOS technology suitable for low cost mixed signal and RF products. TCAD-based simulation results proved the concept with gain as high 100 for a NPN device using single additional mask. Overall, this work has shown that several novel process techniques and selective use of optimum H₂ anneal can lead to various high performance and low cost devices and memory cells those are much better than the devices using current conventional 3D fin based process techniques.

Streszczenie:

Nanotechnology structures are particles with a diameter of 1 to 100 nm in at least one dimension. Nanoparticles are made from a variety of soluble and insoluble materials. The nanotechnology market is expected to expand at a rate of around 17.5 percent per year between 2016 and 2022. New nanomaterials that have been thoroughly characterized are becoming increasingly important in biomedical applications. There's a lot of evidence that nanomaterials do not just communicate with cells passively; they also interact with them actively. For the estimation of toxic endpoints, machine learning (ML) methods and algorithms are commonly used. The ML tools in Nano toxicology enable the combination of a number of knowledge sources containing physicochemical properties and outcomes of in vivo and in vitro toxicity experiments. The goal of this review was to highlight current achievements and point out new methods of evaluation in the field of predicting Nano toxicology.

Streszczenie:

Multiferroic nanomaterials bear draw attention plenty consideration on account of the mixture of two or more determinants, in the way that ferroelectricity, ferromagnetism, and ferroelasticity, giving an expansive range of professional, depressed capacity, environmentally intimate request. Nano-bismuth ferrite (BiFeO3, BFO) exhibits two together (anti) ferromagnetic and ferroelectric real estate at room temperature. Therefore, it bears risk a very influential part fashionable the multiferroic foundation. This review focuses ahead of the progress of nano-BFO objects, containing unification, facial characteristics, structures, and potential uses of multiferroic order accompanying novel functions. Hopes and danger happen all investigated and made clear. We hope that this review will be a part of a review and encourage more research workers to win accompanying nano-BFO results.

Streszczenie:

The impacts of Harmful Algal Blooms (HAB), often caused by cyanobacteria (Figure 1), on water resources are increasing. Innovative solutions for treatment of HABs and their associated toxins are needed to mitigate these impacts and decrease risks without introducing persistent legacy contaminants that cause collateral ecosystem impacts. This technical note (TN) identifies novel opportunities enabled by Additive Manufacturing (AM), or 3D printing, to produce high surface area advanced material composites to rapidly prototype sustainable environmental solutions for aquatic nuisance species control. This innovative research explores deployment of 3D-printable polymer composite structures containing nano-scale photocatalysts for targeted open water treatment of HABs that are customizable to the site-of-concern and also retrievable, reusable, and sustainable. The approach developed to control cyanobacteria HAB events has the potential to augment or replace broadcast, non-specific chemical controls that otherwise put non-target species and ecological resources at long-term risk. It can also augment existing UV-treatment HAB treatment control measures. The expected research outcome is a novel, effective, and sustainable HAB management tool for the US Army Corps of Engineers (USACE) and resource managers to deploy in their HAB rapid response programs. The research will provide a framework for scale-up into other manufacturing methods (e.g., injection molding) to produce the devices in bulk (quickly and efficiently). Research for this project title “Mitigation of Harmful Algal Bloom Toxins using 3D Printed Photocatalytic Materials (FY21-23)” was sponsored by the US Army Engineer Research Development Center’s (ERDC) Aquatic Nuisance Species Research Program (ANSRP).
