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 ...

Normally Off AlGaN/GaN Metal–2DEG Tunnel-Junction Field-Effect Transistors

, 2011
We present the first AlGaN/GaN tunnel-junction FETs (TJ-FETs) featuring a metal2-D-electron-gas (2DEG) Schottky tunnel junction at the source. The control of the source-to-drain current flow is realized through a gate-controlled tunnel junction instead ...

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.

Analytical Modeling of Depletion-Mode MOSHEMT Device for High- Temperature Applications

IEEE Access
An analytical model for depletion-mode MOSHEMTs for high-temperature applications is compared against the experimental GaN HEMT data of the AlGaN/GaN MOSHEMT for temperature dependence of 2DEG simulated at 75 °C and 125 °C.

Polarization induced 2DEG in MBE grown AlGaN/GaN HFETs: On the origin, DC and RF characterization

, 2000
The contribution of spontaneous and piezoelectric polarization to the formation of a 2DEG in AlGaN/GaN heterostructures was investigated using undoped AlGaN/GaN structures.
