Ya. Mityagin et al., ANISOTROPY AND UNIAXIAL-STRESS EFFECTS IN SUBMILLIMETER STIMULATED-EMISSION SPECTRA OF HOT HOLES IN GERMANIUM IN STRONG E-PERPENDICULAR-TO-H FIELDS, Semiconductor science and technology, 7(3B), 1992, pp. 641-644
The light hole cyclotron stimulated emission in p-Ge in strong E perpe
ndicular-to H fields was studied as a function of E and H field orient
ation and uniaxial stress applied to the crystal. Quantum model calcul
ations of light hole scattering rates and Landau level population are
used to interpret the results. The low frequency part of the intersubb
and emission spectra was investigated, and new emission lines were fou
nd. The role of impurity transitions in stimulated emission processes
is discussed.
