Abstract

The effect of a high constant electric field on plasma oscillations in the two-dimensional electron gas of a semiconductor with a superstructure was studied taking into account the Umklapp processes. A dispersion relation for the plasma-oscillation frequency ω(k) was derived for high temperatures (≪, where Δ is the conduction miniband width and T is the temperature in energy units). The plasmon frequency in a high electric field is shown to oscillate as the electric field strength and the wave number k vary. For arbitrary values of k, the spectrum is periodic with a period of 2π/d. Numerical estimates show that the oscillations may manifest themselves at electric field strengths higher than 3×103 V/cm.
