Measurements of Intervalley Phonons in n-Si by Magnetophonon Resonance

Abstract

Oscillatory structures of the longitudinal magnetoconductance in n-Si are investigated at 77 K in the magnetic field up to 8 T applied in the directions <100>, <110> and <111>. Fourier analysis reveals 7 series for B //<100>, 5 series for B //<110>, and 7 series for B //<111>. Various phonon energies for the f - and g -type intervalley scatterings are determined and compared with the results obtained from the neutron scattering data of Dolling.
