Inelastic Light Scattering from Landau-Level Electrons in Semiconductors

Abstract

Inelastic scattering of 10.6-\ensuremath{\mu} C${\mathrm{O}}_{2}$ laser radiation by mobile electrons in a magnetic field has been observed in $n$-InSb. Spectra of the scattered light reveal three distinct lines corresponding to electron spin flip and to transitions with $\ensuremath{\Delta}l=1$ and $\ensuremath{\Delta}l=2$, where $l$ is the Landau-level quantum number. Observations are compared with theoretical predictions and electronic parameters obtainable from the spectra are discussed.
