Abstract:
The electron temperature and electron current as a function of the applied electric field in a semiconductor in a magnetic field are computed for optical phonon scattering and taking into account the three lowest Landau-levels. The decrease of electron temperature below the lattice temperature, electron cooling, is shown to be much stronger in a magnetic field than in its absence. The tendency to current saturation which occurs in polar materials is shown to be more pronounced in a magnetic field. Acoustical phonon- and ionized impurity scattering in strong magnetic field are qualitatively discussed. Author
