✦ Synopsis

A theory for the effects of size quantization and strain on the hole energy spectra in wurtzite AlGaN/GaN/AlGaN quantum wells is presented. The subband structure and dispersion relations for holes in pseudomorphically strained rectangular wells are obtained using an analytical solution of SchrΓΆdinger's equation with 3 Γ— 3 matrix Hamiltonian blocks. The effects of strain are interpreted using an analogy between wΓΌrzite structures and prestrained zincblende crystals.

We present a comparative study of two different spectroscopic techniques in order to determine the valence band offset in \(\mathrm{CdTe} /(\mathrm{CdMn}) \mathrm{Te}\) quantum wells. On the one hand the energy difference between heavy- and light-hole excitons as a function of the heavy-hole transit
