Bloch gain in dc-ac-driven semiconductor superlattices in the absence of electric domains
Timo Hyart, Kirill N. Alekseev, Erkki V. Thuneberg
We study theoretically the feasibility of amplification and generation of terahertz radiation in dc-ac-driven semiconductor superlattices in the absence of electric domains. We fin…

Terahertz Parametric Gain in Semiconductor 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. Action of ac electric field causes oscillations of ele…
