摘要：
A quantum-mechanical calculation of the conduction cyclotron mass in GaAs-(Ga,Al)As superlattices in an in-plane magnetic field is performed. Calculation is carried out in the envelope function approximation using the parabolic and nonparabolic models for the conduction band. The cyclotron mass is studied as a function of the Al concentration x in the barrier for different magnetic fields. A discussion of the influence of nonparabolicity on the x dependence of the cyclotron mass and a comparison with previously reported experimental data are presented. © 1995 American Institute of Physics.
