Photon Assisted Tunneling in ZnSe-ZnTe Double Barrier Heterostructures
Languages of publication
The tunneling phenomena in double barrier heterostructures can be affected by various effects. In this paper the effect of the intense THz radiation on the electron dynamics in the double barrier heterostructure is investigated. For the low frequency radiation the shift in the energy 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 sequential tunneling and the transmitted wave function consists of single separated wave packets.
