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…

THz parametric gain in semiconductor superlattices in the absence of electric domains
Timo Hyart, Natalia V. Alexeeva, Ahti Leppanen +1
We theoretically show that conditions for THz gain and conditions for formation of destructive electric domains in semiconductor superlattices are fairly different in the case of p…
