Abstract
We consider phonon-electron interactions in highly doped III-V and II-VI semiconducting compounds, including nonparabolicity of the conduction band and the spin-orbit interaction. Absorption coefficients are calculated for monochromatic phonons produced by superconducting Sn and Al tunnel junctions, and we predict the possibility of observing directly an interaction of conduction electrons with slow and fast transverse modes, and phonon-induced spin-flip transitions.Keywords
