2D electron gas in chalcogenide multilayers [PDF]
, 2020 Semiconductor interfaces, such as these existing in multilayer structures (e.g., quantum wells (QWs)), are interesting because of their ability to form 2D electron gases (2DEGs), in which charge carriers behave completely differently than they do in the bulk.

Nanomaterials, 2020 Interest in layered two-dimensional (2D) materials has been escalating rapidly over the past few decades due to their promising optoelectronic and photonic properties emerging from their atomically thin 2D structural confinements. When these 2D materials

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.

Evidence for the Josephson Effect in Quantum Hall Bilayers [PDF]
, 2004 This thesis presents tunneling measurements on bilayer two-dimensional (2D) electrons systems in GaAs/AlGaAs double quantum wells. 2D-2D tunneling is applied here as a probe of the inter-layer correlated quantum Hall state at total Landau level filling
