Terahertz Bloch oscillator with suppressed electric domains: Effect of elastic scattering
Timo Hyart, Kirill N. Alekseev, Ahti Leppanen +1
We theoretically consider the amplification of THz radiation in a superlattice Bloch oscillator. The main dilemma in the realization of THz Bloch oscillator is finding operational…

Generation of high-frequency radiation in semiconductor superlattices with suppressed space-charge instabilities
Kirill N. Alekseev, Natalia V. Demarina, Maxim V. Gorkunov
We theoretically investigated the scheme allowing to avoid destructive space-charge instabilities and to obtain a strong gain at microwave and THz frequencies in semiconductor supe…
