Author:Kunert, HW; Machatine, AGJ; Niyongabo, P; Govender, M; Mwakikunga, Bonex WDate:Oct 2012Scattering matrix for two phonon processes at k = 0 in Si and Ge of O(sup7)(subh) symmetry is given. Also diagonalization of spin-orbit interaction Hamiltonian has been computed by means of Clebsh-Gordan coefficients. The authors have concluded ...Read more
Author:Kunert, HW; Govender, M; Machatine, AGJ; Mwakikunga, Bonex W; Niyongabo, PDate:Feb 2014At sufficiently high pressures, wurtzite structure zinc oxide (W-ZnO) can be transformed to the cubic rocksalt (R-ZnO) structure. The R-ZnO exhibits semiconductor behavior with an indirect wide band gap of inline image. The maximum valence ...Read more
