Abstract: | The properties of a high-frequency response in resonant tunneling double-well nanostructures have been considered for various
energies of electrons arriving to a structure of electrons, various frequencies of the external electromagnetic field, and
various features associated with the interaction of electronic states in neighboring quantum wells in double-well nanostructures.
The energy filtration effect that is caused by the breaking of the symmetry of the high-frequency response in double-well
nanostructures in a static electric field has been revealed. This effect leads to a sharp increase in the gain under conditions
of the quantum amplification regime and opens real prospects of a significant increase in the efficiency of solid amplifying
and generating devices based on resonant tunneling double-well nanostructure in the subterahertz and terahertz frequency ranges. |
