ZnO综述文章《properties of ZnO

Abstract. The valence band structure of ZnO at k =0 has been determined by investigating the emission and reflection spectra. The data indicate that the F9 is the top valence band and that the spin-orbit splitting is positive. There appears to be very little exchange correction, thus the exciton spectra is hydrogenic for the T9 and top T7. The Zn d-orbitals, which are approximately 8eV below the top valence bands, have very little effect on the spin-orbit splitting in contrast to CuCl where the Cu d-orbitals cause a negative spin-orbit splitting and a reversal of the top valence band structure. Various calculations using a variety of methods are reviewed and a discussion of the difficulty of obtaining very accurate theorical results is given. This includes first-principle, zero parameter calculations which approximate the exchange-correlation operators, as well as effective mass approximations with a series of experimental adjusted parameters. These calculations have led to a long-standing controversy over the symmetry ordering of the valence bands in ZnO which has lasted for more than 30 years. The recent availability of ZnO crystals in which intrinsic excitontransitions are observed in emission and their splitting in a magnetic field have resolved this controversy.
