Influence of the channel electric field distribution on the polarization Coulomb field scattering in AlGaN/AlN/GaN heterostructure field-effect transistors

AIP Advances, 2013
Using the Quasi-Two-Dimensional (quasi-2D) model, the current-voltage (I-V) characteristics of AlGaN/AlN/GaN heterostructure field-effect transistors (HFETs) with different gate length were simulated based on the measured capacitance-voltage (C-V ...

Currents in the Compressible and Incompressible Regions of the 2DEG

, 1994
We derive a general expression for the low-temperature current distribution in a two-dimensional electron gas, subjected to a perpendicular magnetic field and in a confining potential that varies slowly on the scale of the magnetic length l. The analysis is based on a self-consistent one-electron description, such as the Hartree or standard Kohn-Sham ...

Effect of electrostatic confinement on the dome-shaped superconducting phase diagram at the LaAlO3/SrTiO3 interface

Scientific Reports
The two-dimensional electron gas (2DEG) at the LaAlO $$_3$$ /SrTiO $$_3$$ (LAO/STO) interface exhibits gate-tunable superconductivity with a dome-like shape of critical temperature as a function of electron concentration.

Machine learning methods for background potential estimation in 2DEGs

Physica E: Low-dimensional Systems and Nanostructures
In the realm of quantum-effect devices and materials, two-dimensional electron gases (2DEGs) stand as fundamental structures that promise transformative technologies. However, the presence of impurities and defects in 2DEGs poses substantial challenges, impacting carrier mobility, conductivity, and quantum coherence time.
