Abstract:
R(T, B) of the natural black arsenic (b-As) polycrystal was studied. It was shown that the polycrystalline b-As sample contains the b-As phase and also the traces of its oxide, as well as grey arsenic and arsenolite (As2O3). The behavior of the relative magnetoresistance of the b-As crystal was described by the relation MR(B) = bBn + cBm, where the coefficients b and c and the exponents n and m were also affected by the mechanisms of magnetoresistance formation and temperature. At the temperatures below 10 K, MR(B) shows the presence of a competition between negative (with b < 0 and n ≈ 0.5) and positive (with c > 0 and m ≈ 1) contributions. Above 10 K, only the PMR effect was presented. For the PMR effect, at 10 < T < 100 K it is observed that the values of b > 0, n ≈ 1 and c → 0. Above 100 K, it is observed that the values of b, c > 0 and n ≈ 1 and 1.30 < m < 1.47. The observed behavior of the R(T, B) dependences is associated with strong inhomogeneity and/or disorder of the investigated black arsenic crystal.

AbstractThis paper contains the results of the electric properties measurement of lentil set. Electric measurements with use of these materials are of fundamental importance in relation to the analysis of quantity of absorbed water and dielectric heating characteristics. The aim of this paper was to perform the measurements of conductivity, dielectric constant and loss tangent on samples of lentil, the electrical properties of which had not been sufficiently measured. Measurements were performed under various moisture contents, and the frequency of electric field ranged from 1 MHz to 16 MHz, using a Q meter with coaxial probe. It was concluded that conductivity, relative permittivity and loss tangent increased with an increase in moisture content, and dielectric constant and loss tangent decreased as the frequency of electric field increased.

Cyanoborane isomers and their acyclic and cyclic oligomers serve as useful models for studying properties of molecules with alternating electron-rich and electron-deficient groups. Static electric properties including electronic dipole moment, polarizability, first and second hyperpolarizabilities of three stable isomeric monomers - boranylmethanenitrile, borazirene and 1-(methanylidyne)borazan-1-ium-2-ide - have been calculated at the MP2, CCSD and CCSD(T) levels using various basis sets. In addition, frequency-dependent (hyper)- polarizabilities of the most stable isomer have been evaluated via the CCSD response theory.

Abstract:
Cette thèse présente une étude théorique du transport de chaleur dans les matériaux composites nano poreux et nano fils ainsi qu'une étude théorique des propriétés thermoélectriques de l'alliage Si0:8Ge0:2 confrontée à des mesures expérimentales réalisées pour une partie, dans le cadre de l'étude.La première étude démontre que les alliages poreux affichent des réductions de conductivité thermique à des dimensions de pores beaucoup plus grandes que les matériaux poreux non alliés de même porosité nominale. Si on considère une taille de pores de 1000nm, la conductivité thermique de l'alliage Si0:5Ge0:5 avec 0:1 de porosité est deux fois plus faible que la conductivité thermique d'un matériau non poreux, alors que les pores plus petits que 100 nm sont nécessaires pour obtenir la même réduction relative dans le Si ou Ge pur. Nos résultats indiquent que les alliages nano poreux devraient être avantageux devant les matériaux nano poreux non alliés, et ceux pour les applications nécessitant une faible conductivité thermique, tels que les nouveaux matériaux thermoélectriques.La deuxième étude théorique sur la conductance thermique de nano fils révèle l'effet de la structure sur le transport des phonons. Avec un modèle théorique qui considère la dépendance en fréquence du transport des phonons, nous sommes en mesure quantitativement de rendre compte des résultats expérimentaux sur des nano fils droits et coudés dans la gamme de température qui montre qu'un double coude sur un fil réduit sa conductance thermique de 40% à la température de 5K. Enfin, nous avons procédé à une approche théorique des propriétés thermoélectriques des alliages SiGe frittés, en les comparant aux mesures expérimentales nouvelles et antérieures, tout en évaluant leur potentiel d'amélioration. L'approche théorique a été validée par comparaison de la mobilité prévue et la conductivité thermique prévues, en faisant varier la quantité de Ge et les concentrations de dopage, dans une gamme de température comprise entre 300 et 1000K. Nos calculs suggèrent qu'une optimisation par rapport à l'état de l'art actuel est possible pour le matériau de type n et type p, conduisant potentiellement à une augmentation de 6% (5%) du ZT _a 1000K et 25% (4%) _a température ambiante. Même des améliorations plus grandes devraient être possibles si la probabilité de diffusion des phonons aux joints de grains pouvait être augmentée au-delà de sa valeur actuelle de 10%.

Abstract:
This thesis describes low-temperature transport measurements in low-dimensional systems fabricated in high-mobility GaAs/AlGaAs heterostructures. These low-dimensional systems are formed by electrostatically constricting the electrons in the two-dimensional electron gas at the interface of the heterostructure, by applying a voltage to a pair of metallic gates known as a split-gate. At low temperatures the electrical conduction occurs without scattering. The aim is to measure the thermal conductance of these one-dimensional ballistic conductors. The thermal conductance of a split-gate device was measured as a function of gate voltage, over a wide range of temperatures and in the absence of a magnetic field. The electrons on one side of the constriction were heated with an electric current, and the temperature drop across the split-gate was measured using the thermopower of another split-gate. The measurements show that the thermal conductance displays plateaux corresponding to the one-dimensional subbands, confirming previous results. The design of the samples allows a quantitative test of the Wiedemann-Franz law in one-dimensional constrictions. The results strongly suggest that the Wiedemann-Franz law is satisfied, and new information was obtained regarding the anomaly in the conductance known as 0.7 structure, which can provide a new insight into the nature of this anomaly. It is found that the thermal conductance corresponding to the anomaly is suppressed with respect to the value expected from a single-particle picture.

Abstract:
The first part of the dissertation focuses on understanding and modeling the conduction mechanism of conductive adhesives. The contact resistance is measured between silver rods with different coating materials, and the relationship between tunnel resistivity and contact pressure is obtained based on the experimental results. Three dimensional microstructure models and resistor networks are built to simulate electrical conduction in conductive adhesives. The bulk resistivity of conductive adhesives is calculated from the computer-simulated model. The effects of the geometric properties of filler particles, such as size, shape and distribution, on electrical conductivity are studied by the method of factorial design. The second part of the dissertation evaluates the reliability and investigates the failure mechanism of conductive adhesives subjected to fatigue loading, moisture conditioning and drop impacts. In fatigue tests it is found that electrical conduction failure occurs prior to mechanical failure. The experimental data show that electrical fatigue life can be described well by the power law equation. The electrical failure of conductive adhesives in fatigue is due to the impaired epoxy-silver interfacial adhesion. Moisture uptake in conductive adhesives is measured after moisture conditioning and moisture recovery. The fatigue life of conductive adhesives is significantly shortened after moisture conditioning and moisture recovery. The moisture accelerates the debonding of silver flakes from epoxy resin, which results in a reduced fatigue life. Drop tests are performed on test vehicles with conductive adhesive joints. The electrical conduction failure happens at the same time as joint breakage. The drop failure life is found to be correlated with the strain energy caused by the drop impact, and a power law life model is proposed for drop tests. The fracture is found to be interfacial between the conductive adhesive joints and components/substrates. This research provides a comprehensive understanding of the conduction mechanism of conductive adhesives. The computer-simulated modeling approach presents a useful design tool for the conductive adhesive industry. The reliability tests and proposed failure mechanisms are helpful to prevent failure of conductive adhesives in electronic packages. Moreover, the fatigue and impact life models provide tools in product design and failure prediction of conductive adhesives.

Abstract:
Aniline Black, a polymer containing p-benzoquinodiimine groups, was synthesized chemically or electrochemically by the oxidation of aniline. The polymer salts showed the conductivity of 10⁻¹-10⁻³ ohm⁻¹cm⁻¹. Polymers containing anthroquinodiimine units were also prepared by polycondensations. The syntheses of model compounds containing p-benzoquinodiimine were attempted. Multiazobisphenol monomers were synthesized. 4,4'-(3,3'-Dimethyl-4,4'-biphenylenebisazo) bisphenol 7, 4,4'-[azobis(p-phenyleneazo)] bisphenol 8, and 4,4'-(2-methoxy-1,4-phenylenebisazo) bisphenol 10 displayed liquid crystal (l.c.) properties, while model derivatives of 7, 8, and 4,4'-(4,4'-stilbenebisazo) bisphenol 9 did likewise. Monomers and derivatives of 4-[(4-hydroxyphenyl)azo]-1-naphthol 5, and 4,4'- [oxybis(p-phenyleneazo)] bisphenol 6 showed no l.c. behavior. New thermotropic polyesters based on these multiazobisphenols were synthesized. Sebacates of 5, 6, 7, 8, and 10 showed l.c. behavior, while polymers based on isophthalic or 5-t-butylisophthalic acid did not do so. Polyformals were also synthesized from these momoners, only that of 4 showed weak l.c. behavior. The correlation between the structure of these polymers and their tractabilities, electrical properties, liquid crystal behaviors was studied. Polymers and copolymers containing p-azoarylene and p-azoxyarylene groups were synthesized by oxidative coupling of various aromatic diamines. Films were cast directly from the reaction mixtures or from the polymer solution. The films were n-doped by sodium naphthalide or p-doped by iodine. They showed electrical conductivities of 10⁻⁴ to 10⁻⁵ ohm⁻¹cm⁻¹. AB monomers containing dipolar p-phenyleneazo groups were synthesized: 4-(4-hydroxy-2-methoxyphenylazo) benzoic acid 21, 4-[4-(4-hydroxy-2-methoxyphenylazo)-2-methoxyphenylazo] benzoic acid 22, and 4-(4-hydroxy-2-methoxyphenylazo)-3-nitrobenzoic acid 23. The monomers were polymerized by direct polycondensations. The polyester synthesized from 21 formed a red, transparent film. A polymethacrylate containing dipolar p-phenyleneazo groups in the side chains was also prepared by the free radical polymerization of 1- [3-methoxy-4-(p-nitrophenylazo)-phenoxy] hexyl methacrylate 28.

Abstract:
Ultraviolet photoemission spectroscopy measurements reveal that there is notable variation of the electron density of states in valence bands near the Fermi level. Evolution of the electronic structure of fluorinated graphene as a function ofthe applied electric bias is investigated. The experimental results demonstrate that the tailoring of electronic band structure correlates with the interlayer coupling tuned by the applied bias. The change in the work function of fluorinated graphene demonstrates the ability of fluorination to modify electron emissions characteristics of graphene.

Full text
Abstract:
In optical telecommunications there is a great demand for materials whose optical propagation properties can be influenced by electric fields. For slow switching rates liquid crystals can be used which have extremly high electrooptical coefficients due to mobility of the whole molecule. For higher switching rates electronic properties can be used like POCKELS effect and KERR effect. In order to implement these effects in a polymeric material, this can be doped by a suitable dye in relative small concentrations. The orientation behaviour of pure poly-(alpha-methyl-styrene) (PaMS) has been reported by Muto et al. (1); Singer et al. (2) have studied the electro- optical effect of organic dyes in poly-(methyl-methacrylate) (PMMA) using extremly high electric fields (some 100 V/μm). This paper reports on a study of the electrooptic behaviour of N,N-dihexyl-4-amino-4’-nitro-stilbene, called D 90/87, in PaMS and PMMA.

Full text
Abstract:
The results of fully three-dimensional direct numerical simulations of the effects of electric fields on emulsions of drops will be displayed. The examination of the rheological properties of these systems is performed by imposing a simple-shear flow between two plates where the drops are immersed. An electric potential difference is applied perpendicular to the plates. The resulting electric field leads to two effects: a polarization of the drops and a viscous fluid motion on the interface between the drops and the suspending fluid. The direction and intensity of the viscous fluid motion depends on the electrical properties of the fluids. Drops more conductive than the suspending fluid exhibit a viscous fluid motion from the equator to the poles, whereas drops less conductive than the suspending fluid exhibit a viscous fluid motion from the poles to the equator. The numerical simulations show that the response of the emulsions is governed by the competition between the electric attraction and the fluid shear. The former leads to the aggregation of the drops in chains parallel to the electric field, while the latter tries to break-up the aggregated chains. The results are presented as a function of the Mason number and the electric capillary number, Mn and Ce. These non-dimensional numbers quantify the strength of the electric forces versus the fluid shear and the capillary forces, respectively. The significance of the electrical field on the viscosity and the normal stress differences will be discussed: At low Mason numbers, Mn<0.1, the application of the electric field results in the aggregation of the drops. This aggregation leads to an increase in the effective viscosity of the system and to an increase in the stresses, which result in higher normal stress differences than in hydrodynamic emulsions. At high Mason numbers, Mn>1.0, the fluid shear breaks up the aggregated structures and the properties are similar to hydrodynamic emulsions. At 0.1<Mn<1.0 the properties of the emulsions exhibit an intermediate behavior.

Abstract:
Doping superlattices, also called nipi superlattices, consist of thin alternating n- and p-doped layers of semiconductor material. This periodic doping profile leads to a periodic electric potential perpendicular to the layers. Potential wells for electrons are in the n-type layers, while potential wells for the holes are in the p-type layers. The periodic potential creates an effective band gap in real space, smaller in energy than the direct gap, which is a function of the density of confined carriers, the impurity doping density, and the thickness of the layers. When mobile electrons and holes are generated, they become spatially separated by the electric potential, screen the oppositely charged ionized dopants in their respective wells, and increase the effective band gap. The resulting tunability of electronic states and optical absorption characteristics as a function of carrier density have been investigated theoretically by Döhler and Ruden.1,2

Full text
Abstract:
Image amplification using photorefractive two-wave mixing is attractive since high gain and high signal-to-noise ratios are achievable using relatively low-power lasers. Huignard et. al. have achieved high gains in Bi12SiO20 (BSO) using the DC field and moving grating technique1. The disadvantages of this technique are the uniform illumination and external frequency shift requirements. Another option is the use of alternating electric fields as suggested by Stepanov and Petrov2. This technique has been demonstrated in BTO2 and GaAs3. It maintains the 90o phase shift between the incident fringe pattern and holographic grating required for image amplification, while allowing enhancement of the refractive index change via the external field. Other advantages include increased stability, no requirement for uniform illumination, and the avoidance of the electrode "shadowing" problem. In addition, the trap saturation regime (i. e. the maximum possible grating amplitude for a given material) can be reached at very high fields. The application of this technique to BSO has been suggested previously2,3,4, and preliminary results are presented here.

Full text
Abstract:
This paper describes a new class of optical nonlinearities which can be important in semiconductors. This nonlinearity relies on the motion of optically-excited carriers due to internal fields within the semiconductor. Such fields can exist. for example. in semiconductor depletion regions. The charge motion sets up a resultant space charge which acts opposite to the internal fields, reducing their value. The resultant decrease in electric field changes the absorption and/or refractive index through electro-absorption, electro-refraction, electro-optic effect or quantum confined Stark effect, depending on the geometry. To understand these new nonlinearities, we draw from concepts of photorefractivity, n-i-p-i structures, the quantum confined Stark effect (QCSE) in multiple quantum wells (MQW), and relations to the self-electro-optic effect device (SEED).

Abstract:
In recent years, several pipe mills have produced heavy-wall, large diameter pipe from plates of microalloyed steels that were controlled-rolled to develop properties to meet the API 5LX Grade 70 or Grade 80 requirements and that were electric resistance welded (ERW) using advanced techniques. The use of advanced electric seam-welding practices on the steels produced using advanced steel making and processing methods offers the possibility of obtaining high strength line pipe at a lower cost than pipes produced from similar steels but with double submerged arc seam welds. The present study was undertaken to evaluate the properties of the pipe body and the ERW seam-weld region of a recently produced heavy-wall X70 line pipe. This report describes the evaluation of that pipe. The mechanical properties of the weld zone from this pipe were evaluated and reported under Task 18-89. Those data are included in this report. A high-frequency electric resistance welded (HFERW) X70 line pipe was evaluated to assess the strength properties, fracture behavior, thermal stability, and susceptibility to environmentally induced degradation that may affect its behavior in gas transmission service. A 20-inch-(508 mm)-diameter by 0.500-inch-(12.7 mm)-wall high-frequency, electric-resistance-welded (HFERW) X70 line pipe was evaluated to assess the strength properties, fracture behavior, thermal stability, and susceptibility to environmentally induced degradation that may affect its behavior in gas transmission service. The steel from which the pipe was produced was processed using advanced steel-making practices that resulted in a low sulfur content and was microalloyed with Cb, V, and Ti. The steel was controlled rolled with 75 percent of the rolling reduction being accomplished at temperatures below 1418 F (770 C); the finishing temperature was 1328 F (720 C) and the steel was hot coiled after finishing. The seam weld was produced by high frequency electric resistance welding and the seam weld region was post-weld normalized.

Full text
Abstract:
In contrast to conventional powertrains from internal combustion engine vehicles (ICEV), the tribological performance of powertrains of electric vehicles (EVs) must be further evaluated by considering new critical operating conditions such as electrical environments. The operation of any type of electric motor produces shaft voltages and currents due to various hardware configurations and factors. Furthermore, the common application of inverters intensifies this problem. It has been reported that the induced shaft voltages and currents can cause premature failure problems in tribological components such as bearings and gears due to accelerated wear and/or fatigue. It is ascribed to effects of electric discharge machining (EDM), also named, sparking wear caused by shaft currents and poor or increasingly diminishing dielectric strength of lubricants. A great effort has been done to study this problem in bearings, but it has not yet been the case for gears. Considering that EVs powertrains can be configurated with an electric motor coupled to a single-speed or multi-speed transmission, it is expected that shaft currents can also affect gears to some extent. The pin-on-disc test has been widely used to study sliding wear of gear materials under comparable or realistic operating conditions. This accelerated test is effective for screening materials, lubricants and operating conditions allowing evaluations of their friction and wear properties. However, it has not been implemented for studying gear materials under electrified environments. Thus, this paper aims to explore the friction coefficient and wear of gear materials under non-electrified and electrified sliding in a pin-on-disc tester applying typical of EVs powertrain shaft currents during sliding. The tests were carried out at two different DC currents under comparable gear dry and lubricated sliding contact conditions. Friction coefficient, wear volumes and morphologies were evaluated and reported in this work.
