Magnetophonon Resonance of Hot Electrons inn-InSb at 77°K

Abstract

Magnetophonon resonances in the hot-electron mobility have been observed in pure $n$-InSb at 77°K in transverse magnetic fields with the application of sufficiently small voltage to produce a slight change in the mobility. The minima in the quantity $\beta$ in the formula $\mu ={\mu }_0(1-\beta E^2)$ are attributed to resonant cooling of hot electrons due to optical-phonon-induced transitions between Landau levels.
