Dynamics of electron scattering in absolutely transparent channels in three-barrier structures in the case of two-photon transitions

Аннотация

Solution of the Schrödinger equation, which describes resonant transitions between three quantum levels in large-signal and high-frequency electric fields, is generalized to the case of the detuning of frequencies and energies from those exactly resonant for asymmetric three-barrier resonance-tunneling structures with thin high barriers. The dependence of the shape of the resonance levels on the amplitude and frequency of electric fields is studied. It is shown that the number of regions of absolute transparency can be as large as four depending on the microwave-field amplitude.
