Model of the Influence of an External Magnetic Field on the Gain of Terahertz Radiation from Semiconductor Superlattices
Timo Hyart, Jussi Mattas, Kirill N. Alekseev
We theoretically analyze the influence of magnetic field on small-signal absorption and gain in a superlattice. We predict a very large and tunable THz gain due to nonlinear cyclot…

Terahertz Bloch oscillator with a modulated bias
Timo Hyart, Natalia V. Alexeeva, Jussi Mattas +1
Electrons performing Bloch oscillations in an energy band of a dc-biased superlattice in the presence of weak dissipation can potentially generate THz fields at room temperature. T…
