Anomalous suppression of the probability of resonance interaction of electrons with an rf field in asymmetric double-barrier structures on account of plasma oscillations

An analytical self-consistent solution of the nonstationary Schrödinger and Poisson equations describing the resonance interaction of electrons with a radio-frequency (rf) field has been found for asymmetric resonance-tunneling structures with high, thin barriers. It is shown that plasma oscillations limit the probability of transitions between neighboring levels and suppress anomalously strongly transitions in which the level number changes by more than 1 (by tens and hundreds of times compared with transitions between neighboring levels).
