High-Field Resonant Magnetotransport Measurements in Smalln+nn+GaAs Structures: Evidence for Electric-Field-Induced Elastic Inter-Landau-Level Scattering

Abstract

Magnetophonon resonance at high electric fields in thin (1 to 9 μm) $n^{+}$ $n{n}^{+}$ GaAs structures reveals a new mechanism of magnetoconduction, in which an electron in the $n\mathrm{th}$ Landau level can scatter elastically or quasielastically into the $\mathrm{}(n+1\mathrm{})\mathrm{}\mathrm{th}$ level.
