Abstract

The Landau level structure of the degenerate valence band of silicon in crossed electric and mag netic fields (B = 5 T, E = 0 to 5 kV cm(-1)) has been calculated using the complete effective mass Hamiltonian for the three valence subbands. The calculations reveal a population inversion between light hole Landau levels at cryogenic temperatures due to a strongly level-dependent scattering on optical phonons, which is caused by quantum mechanical mixing of light and heavy hole states in crossed E and B fields. The possibility of amplification of far-infrared radiation on light hole cyclotron resonance transitions is discussed.
