A Curved Noninteracting 2D Electron Gas with Anisotropic Mass [PDF]
Annalen der Physik, 2018 AbstractIn da Costa's thin‐layer approach, a quantum particle moving in a 3D sample is confined to a curved thin interface. At the end, the interface effects are ignored and the quantum particle is localized on a curved surface. A geometric potential arises and, since it is due to this confinement procedure, it depends on the transverse to the surface ...

Lateral Gating of 2D Electron Gas in Cross‐Sectional LaAlO3/SrTiO3
Advanced Electronic Materials, 2020 2D electron gas at LaAlO3/SrTiO3 (LAO/STO) interfaces has emerged as an attractive platform for novel nanoelectronic devices. Control over the active functional interface by electrical or mechanical means in this regard is of special interest.

Competing electronic states emerging on polar surfaces
Nature Communications, 2022 Defect-free surfaces with excess charge are typically described as a homogeneous 2D electron gas. Here, in contrast, the authors find that the KTaO3(001) surface hosts a charge density wave coexisting with a pattern of electron polarons, highly localized

Comment on “Antilocalization in a 2D Electron Gas in a Random Magnetic Field” [PDF]
Physical Review Letters, 2001 In a recent Letter, Taras-Semchuk and Efetov reconsider the problem of electron localization in a random magnetic field in two dimensions. They claim that due to the long-range nature of the vector potential correlations an additional term appears in the effective field theory ($σ$-model) of the problem, leading to delocalization at the one-loop level.

Effect of surface charge self-organization on gate-induced 2D electron and hole systems [PDF]
Modern Electronic Materials, 2020 A simple model has been suggested for describing self-organization of localized charges and quantum scattering in undoped GaAs/AlGaAs structures with 2D electron or hole gas created by applying respective gate bias. It has been assumed that these metal /

Thermal generation of shift electric current
New Journal of Physics, 2020 It is shown that the dissipation of energy in an electron gas confined in a quantum well made of non-centrosymmetric crystal leads to a direct electric current.
