%X We present a k.P theoretical study of the energy band properties of würtzite ZnO/Zn1−xMgxO Quantum Well Heterostructures (QWH) as a function of the alloy composition x in the range x<0.4, and for various well widths. For this purpose, we use a Luttinger-type effective mass model, the 6×6 Rashba–Sheka–Pikus model, to describe the valence bands of these QWH. By using the k.P parameters available in the literature, we have first computed the energy band-structure dispersion of bulk ZnO and we have found good agreement with previous k.P, as well as, ASA-LMPTO results. Then we have computed the valence band dispersion and confinement energies in the range of interest x<0.40 and for various well widths LZ. Good agreement is found with the available pump–probe PL results, for the peak energies of linear absorption for various QWH are closely fitted.
