Optoelectronic transport through quantum Hall edge states

New Journal of Physics, 2015
We use GaAs-based quantum point contacts as mesoscopic detectors to locally analyze the flow of photogenerated electrons in a two-dimensional electron gas (2DEG) at perpendicular, quantizing magnetic fields.

Electron Band Structure in a Two Dimensional Periodic Magnetic Field

, 1994
In this paper we study the energy spectrum of a two dimensional electron gas (2DEG) in a two dimensional periodic magnetic field. Both a square magnetic lattice and a triangular one are considered. We consider the general case where the magnetic field in

Formation of oxygen vacancy at surfaces of ZnO by trimethylaluminum

APL Materials
The two-dimensional electron gas (2DEG) is a group of electrons that can move freely in horizontal dimensions but are confined in the third direction. It has been reported that atomic layer deposition (ALD) of Al2O3 on various reducible n-type oxides can

Atomically flat interface between a single-terminated LaAlO3 substrate and SrTiO3 thin film is insulating

AIP Advances, 2012
The surface termination of (100)-oriented LaAlO3 (LAO) single crystals was examined by atomic force microscopy and optimized to produce a single-terminated atomically flat surface by annealing.

Cooling electrons by magnetic-field tuning of Andreev reflection

, 2006
A solid-state cooling principle based on magnetic-field-driven tunable suppression of Andreev reflection in superconductor/two-dimensional electron gas nanostructures is proposed.

Localization of electronic states in 2DEG under spatially local gradient magnetic field

AIP Advances, 2018
Based on the tight-binding method, we investigate the energy spectrum and localization of electronic states in 2DEG subjected to a spatially local gradient magnetic field.

Energy Transfer Rate in Double-Layer Graphene Systems: Linear Regime

, 2012
We investigate theoretically the energy transfer phenomenon in a double-layer graphene (DLG) system in which two layers are coupled due to the Coulomb interlayer interaction without appreciable interlayer tunneling.

Impact of biased cooling on the operation of undoped silicon quantum well field-effect devices

AIP Advances
Gate-tunable semiconductor nanosystems are getting more and more important in the realization of quantum circuits. While such devices are typically cooled to operation temperature with zero bias applied to the gate, biased cooling corresponds to a non ...
