摘要：
The energy-wave-vector dispersion curves and cubic anisotropy of the confined hole subbands of a (001) AlAs/GaAs/AlAs valence-band quantum well are studied in resonant magnetotunneling experiments using pulsed magnetic fields up to 41 T. The experimental results are compared with calculations using a six-band model which includes the effect of the finite electric field in the quantum well. The comparison convincingly demonstrates that the technique is sufficiently accurate to measure fine details of the band structure of the valence-band quantum well.
