Nonlocal ballistic and hydrodynamic transport in two-dimensional electron systems
… diffusive, due to dominant momentum-relaxing scattering of carriers with the phonons or defects. In ultraclean material systems such as GaAs/AlGaAs or graphene/hBN heterostructures, momentum-relaxing can be suppressed, leading to the onset of non-diffusive transport regimes, where Ohm's law is …

Hydrodynamic and ballistic transport in high-mobility GaAs/AlGaAs heterostructures
The understanding and study of electron transport in semiconductor systems has been the instigation behind the growth of semiconductor electronics industry which has enabled technological developments that are part of our everyday lives. However, most materials exhibit diffusive electron transport …

Monte Carlo Calculations of Parallel and Perpendicular Electron Transport in Gallium-Arsenide Heterolayers
… steady-state transport at low temperatures for electrons in GaAs single well heterojunction structures were performed. This work contains the most complete numerical study in terms of electronic states and scattering mechanisms for these important artificial semiconductor structures. Polar …

Novel transport regimes in graphene
… due to a rich and complex interplay between electron-disorder, electron-electron, and electron-phonon interactions. Graphene, a newly discovered carbon one-atom-thick material, has unique transport characteristics, some of which are already well understood, whereas some are being under …

Effects of doping on the electronic properties of niobium triselenide
The results of magnetization, Electron Spin Resonance(ESR), and electrical resistivity measurements on both undoped and doped samples of the Charge Density Wave (CDW) material NbSe3 are reported. The magnetic studies show that both magnetic(V) and nonmagnetic(Ta) impurities may be introduced into …

Electrical transport and superconductivity in doped quantum critical ferroelectrics
… to be attributed to conventional Fermi-liquid electron-electron scattering. The results of resistivity measured under high pressure are presented which indicate a potential relation to quantum criticality. A theoretical model is presented based on the idea that electrons can scatter from …

Topics in low temperature Fermi liquid theory
… and transport properties of the heavy electron system UPt3. The elementary excitation spectrum of ordinary liquid 3 He is calculated at several pressures using the polarization potential theory of Aldrich and Pines together with a simple model to describe the effect of multipair …

Laterally confined THz sources and graphene based THz optics
… of the applications. This is because of the electron-electron scattering and heating of the 2-dimensional free electron gas which leads to significant optical phonon scattering of the hot electrons. Theoretical studies in laterally confined QCL structures have predicted enhanced lifetime of …

Modeling of Thermal Transport Properties in Metallic and Oxide Fuels
… atoms at bubble surface causes additional phonon scattering and thus further reduces the thermal conductivity. For metallic fuels, temperature gradient and irradiation induced constituent redistribution in U-Zr based fuels cause the variation in fuel composition and the formation of different …
