We calculate the hole energy band structure in GaAs-AlAs Quantum Wells
(QWs) in high in-plane magnetic fields and simulate Resonant Magnetot
unneling Spectroscopy (RMS) experiments, recently proposed as a probe
of the hole energy dispersion. We find that the high magnetic fields u
sed in RMS result in small modifications of the QW hole subbands in th
in QWs. However, for wide QWs or very large magnetic fields, the field
strongly affects the hole dispersion by changing the heavy hole-light
hole mixing. We give a simple expression to evaluate to which extent
the mixing is modified as a function of the QW width and field strengt
h.
