| 英文摘要 | The band structures of wurtzite zno are calculated using the empirical pseudopotential method (epm). the 8 parameters of the zn and o atom pesudopotential form factors with schluter's formula are obtained. the effective mass parameters are extracted by using k.p hamiltonian to fit the epm results. the calculated band edge energies (e-g, e-a, e-b, and e-c) at gamma point are in good agreement with experimental results. the ordering of zno at the top of valence band is found to be a(gamma(7))-b(gamma(9))-c(gamma(7)) due to a negative spin-orbit (so) splitting. based on the band parameters obtained, the valence hole subbands of wurzite zno/mgxzn1-xo tensile-strained quantum wells (qws) with different well widths and mg compositions are calculated using 6-band k.p method.
