Space Charge Waves in A 2DEG

2021 IEEE International Conference on Plasma Science (ICOPS), 2021
The interaction of two-dimensional electron gas (2DEG) in a solid-state heterostructure with a surrounding slow wave circuit holds the potential for high power THz generation and amplification. The dense 2DEG formed at material interfaces will provide an ideally confined beam of high-density electrons, where problems pertinent to the vacuum electron ...

RESPONSE OF A 2DEG TO MICROWAVE IRRADIATION

International Journal of Modern Physics B, 2007
In this paper, we study the behavior of a high mobility two dimensional electron gas under microwave irradiation by means of magneto-photoluminescence (PL) and absorption measurements. The high mobility sample investigated is a 15nm wide GaAs/AlGaAs quantum well with an electron concentration between 1-2×1011 cm -2, tunable by visible-light ...

Quantum resistance standards with double 2deg

IEEE Transactions on Instrumentation and Measurement, 2003
We have developed a new generation of quantum Hall array resistance standards (QHARS) obtained from GaAs/AlGaAs heterostructures with double two-dimensional electron gases (2DEGs) grown by the metal-organic vapor phase epitaxy process. We have achieved the fabrication of such a multilayer system with well matched carrier density and mobility of the two

Heat capacity of a 2DEG

Physica B: Condensed Matter, 1998
We review recent heat capacity experiments performed on GaAs/AlGaAs heterostructures containing two-dimensional electron layers. Near v=1, the strong coupling to the nuclear spin system attributed to Skyrmion-induced low-energy spin excitations has a dramatic effect on the heat capacity which rises by orders of magnitude.

Excitations of a drifting 2DEG

Solid-State Electronics, 1996
Abstract Results are presented on spatially resolved Raman scattering and photoluminescence measurements of a drifting two-dimensional electron gas. Under drifting conditions, a low energy feature is observed in polarized Raman scattering in addition to the intrasubband plasmon mode, and was found to disperse linearly with in-plane wavevector.
