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
Author:Kunert, HW; Machatine, AGJ; Niyongabo, P; Govender, M; Mwakikunga, Bonex WDate:Aug 2012The selection rules (SR’s) for the Kronecker product (KP) of Si and Ge irreducible representations (irreps) are required to determine the intervalley scattering processes. The SR’s for transitions between the lowest conduction band minima at ...Read more
