Coexistence of Bloch and Parametric Mechanisms of High-Frequency Gain in Doped Superlattices
The detailed theoretical study of high-frequency signal gain, when a probe microwave signal is comparable to the AC pump electric field in a semiconductor superlattice, is presented. We identified conditions under which a doped superlattice biased by both DC and AC fields can generate or amplify hig...
