Phase coherent transport and spin-orbit interaction in GaAs/InSb core/shell nanowires
P. Zellekens, N. Demarina, J. Janßen +7
Low-temperature magnetotransport measurements are performed on GaAs/InSb core-shell nanowires. The nanowires were self-catalyzed grown by molecular beam epitaxy. The conductance me…

Suppressed absolute negative conductance and generation of high-frequency radiation in semiconductor superlattices
Kirill N. Alekseev, Maxim V. Gorkunov, Natalia V. Demarina +3
We show that space-charge instabilities (electric field domains) in semiconductor superlattices are the attribute of absolute negative conductance induced by small constant and lar…

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…
