The absorption coefficient for surface acoustic waves in a piezoelectric insulator in contact with a GaAs/AlGaAs heterostructure (with two-dimensional electron mobility $\mu= 1.3\times 10^5 cm^2/V\cdot s)$ at T=4.2K) via a small gap has been investig

Report

Heating of a two-dimensional electron gas by the electric field of a surface acoustic wave

Autor: Drichko, I. L., D'yakonov, A. M., Kagan, V. D., Kreshchuk, A. M., Polyanskaya, T. A., Savel'ev, I. G., Smirnov, I. Yu., Suslov, A. V.

The heating of a two-dimensional electron gas by an rf electric field generated by a surface acoustic wave, which can be described by an electron temperature $T_e$, has been investigated. It is shown that the energy balance of the electron gas is det

Report

The nonlinear effects in 2DEG conductivity investigation by an acoustic method

Autor: Drichko, I. L., Diakonov, A. M., Kagan, V. D., Kreshchuk, A. M., Polyanskaya, T. A., Savel'ev, I. G., Smirnov, I. Yu., Suslov, A. V.

The parameters of two-dimensional electron gas (2DEG) in a GaAs/AlGaAs heterostructure were determined by an acoustical (contactless) method in the delocalized electrons region ($B\le$2.5T). Nonlinear effects in Surface Acoustic Wave (SAW) absorption
