AbstractThe resonances of a resonant tunneling structure are probed by a magnetic field applied parallel to the interfaces, which enables us to investigate the local band structure in k space. By rotating the magnetic field in the plane of the interfaces, the energy surface at constant k is investigated. Using this technique we have studied differently strained Si/Si1-xGex quantum wells; we see a large anisotropy of the energy levels, with the symmetry axes of light holes and heavy holes being rotated 45°with respect to each other. © 1991 The American Physical Society.
