Abstract
A theory for the effects of size quantization and strain on the hole e nergy spectra in wurtzite AlGaN/GaN/AlGaN quantum wells is presented. The subband structure and dispersion relations for holes in pseudomorp hically strained rectangular wells are obtained using an analytical so lution of Schrodinger's equation with 3 x 3 matrix Hamiltonian blocks. The effects of strain are interpreted using an analogy between wurzit e structures and prestrained zincblende crystals. (C) 1997 Academic Pr ess Limited.
