摘要：

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 Schrodinger's equation with 3 x 3 matrix Hamiltonian blocks. The effects of strain are interpreted using an analogy between wurzite structures and prestrained zincblende crystals. (C) 1997 Academic Press Limited.
