Theory of parametric amplification in in superlattices
Timo Hyart, Alexey V. Shorokhov, Kirill N. Alekseev
We consider a high-frequency response of electrons in a single miniband of superlattice subject to dc and ac electric fields. We show that Bragg reflections in miniband result in a…

Quantum derivatives and high-frequency gain in semiconductor superlattices
A. V. Shorokhov, K. N. Alekseev
We derive simple difference formulas describing a small-signal absorption of THz field in a semiconductor superlattice driven by a microwave pump. We give a transparent geometric i…
