The band structures of wurtzite ZnO are calculated by the empirical pseudopotential method EPM . The eight parameters of the Zn and O atomic pseudopotential form factors are obtained with the formula of Schluter et al. Phys. Rev. B 12, 4200 1975 . The band parameters are extracted by using a k· p Hamiltonian to fit the EPM results. The calculated band-edge energies Eg, EA, EB, and EC at the point are in good agreement with the experimental results. Based on the band parameters obtained, valence subbands of wurtzite ZnO/MgxZn1−xO tensile-strained quantum wells with different well widths and Mg compositions are calculated by the six-band k· p method.
