PHOTON-ASSISTED TUNNELING IN ZNSE-ZNTE DOUBLE-BARRIER HETEROSTRUCTURES

The tunneling phenomena in double barrier heterostructures can be affe cted by various effects. In this paper the effect of the intense THz r adiation on the electron dynamics in the double barrier heterostructur e is investigated. For the low frequency radiation the shift in the en ergy scale of the resonant tunneling peak together with its broadening is observed. For the high radiation frequency the multipeak structure is obtained. The interaction with radiation quanta leads to sequentia l tunneling and the transmitted wave function consists of single separ ated wave packets.
