Optically Active Lattice Vibrations of Zinc Blende Type and Wurtzite Type Crystals
Abstract
Normal coordinate treatment has been made of the optically active lattice vibrations of zinc-blende-type and wurtzite-type crystals. Based upon the results of this treatment and upon the observed lattice frequencies, discussions are given on the force constants of cubic and hexagonal silicon carbides, zinc blende, wurtzite, and a few other crystals having the same type of crystal structure with either one of the above two. The hydrogen-bond stretching force constant in hexagonal ice whose crystal structure is similar to that of wurtzite has been estimated to be 0.18 mdyn/%Aring;.
