Mobility of 2D electron gas in polar semiconductors
AIP AdvancesAnalytical expressions for the low-field mobility of two-dimensional electron gas (2DEG) are obtained on the basis of quantum kinetic approach. Calculations and experimental data show that the acoustic and polar optical phonons and ionized impurities are

MAGNETIZATION OF A BILAYER 2D ELECTRON GAS [PDF]
International Journal of Modern Physics B, 2004 We present torque-magnetometry measurements of a bilayer two-dimensional electron gas (2DEG) with an inter-well barrier thin enough to enable a strong coupling between the quantum wells. We observe magnetization steps related to symmetric–anti-symmetric (SAS) transitions. Increasing the in-plane magnetic field leads to a reduction of the SAS splitting.

Correlation Energy and Spin Polarization in the 2D Electron Gas [PDF]
Physical Review Letters, 2002 The ground state energy of the two--dimensional uniform electron gas has been calculated with fixed--node diffusion Monte Carlo, including backflow correlations, for a wide range of electron densities as a function of spin polarization. We give a simple analytic representation of the correlation energy which fits the density and polarization dependence

Thermometer for the 2D Electron Gas using 1D Thermopower [PDF]
Physical Review Letters, 1998 We measure the temperature of a 2D electron gas in GaAs from the thermopower of a one-dimensional ballistic constriction, using the Mott relation to confirm the calibration from the electrical conductance. Under hot electron conditions, this technique shows that the power loss by the electrons follows a $T^5$ dependence in the Gruneisen-Bloch regime ...

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

Formation and Tuning of 2D Electron Gas in Perovskite Heterostructures [PDF]
physica status solidi (b), 2019 Oxide interfaces provide very intriguing phenomena, in particular a 2D electron gas (2DEG) emerging between robustly insulating perovskites. The 2DEG was detected in 2004 beneath polar LaAlO3 (LAO) epitaxially grown on TiO2‐terminated SrTiO3 (001) (STO). Herein, recent first‐principles studies of 2DEGs are reviewed.
