Plasma oscillations in two-dimensional semiconductor superstructures in the presence of high-frequency electric field
The effect of a high-frequency field on plasma oscillations in two-dimensional electron gas with a superstructure was studied. A dispersion relationship ω( k ) was derived in the case of high temperatures (Δ ≪ T , where Δ the conductivity miniband width and T is the temperature in energy units). The...

Summary: | The effect of a high-frequency field on plasma oscillations in two-dimensional electron gas with a superstructure was studied. A dispersion relationship ω(
k
) was derived in the case of high temperatures (Δ ≪
T
, where Δ the conductivity miniband width and
T
is the temperature in energy units). The calculations were based on the quantum theory of plasma oscillations in the casual-phase approximation while taking into account the umklapp processes. |
