摘要
The solution of the quantum transport equation is used to calculate the longitudinal magnetoresistance of a strongly degenerate semiconductor with a superlattice subjected to a magnetic field parallel to the superlattice axis. In the case of inelastic scattering by optical phonons in a quantizing magnetic field an additional series of oscillations of the longitudinal magnetoresistance appears and its period is independent of the optical phonon frequency; such a series is not exhibited by semiconductors with an infinitely wide conduction band. The magnetophonon oscillations are in this case aperiodic in respect of the reciprocal of the magnetic field. In the mixed scattering case the amplitude of the longitudinal magnetoresistance oscillations is proportional to the relaxation time for the second scattering mechanism and for the scattering by optical phonons.
