  • Elementary excitations in Si, Ge, and diamond time reversal affected 
    Kunert, Herbert W.; Machatine, Augusto Gonçalo Jose; Malherbe, Johan B.; Barnas, J.; Hoffmann, A.; Wagner, M.R. (Elsevier, 2008)
    The Space Symmetry and the Time Reversal Symmetry of vibrational modes in Si, Ge and diamond are investigated. Using Space Symmetry we have derived the Lattice Mode Representation. Reducing it onto phonon species we obtain ...
