摘要：

We have carried out full-scale semi-empirical relativistic pseudopotential calculations of the frequency dependence spanning the midinfrared to far infrared range of frequencies-of chi(2) (-2omega;omega,omega) associated with excitations between valence minibands in p-type GaAs-AlAs and Si-SiGe heterostructures. We find that the spectrum is dominated by excitations lying further from the center of the Brillouin zone and depends on states lying above the semiclassical barrier.
