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; 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
