Abstract:

The anisotropic spectra of edge absorption, photoconductivity, emission, and reflectivity of the tetragonal ZnP2 and CdP2 crystals have been experimentally investigated in the range 1 to 12.5 eV. The selection rules for interband transitions, the points of zero slope, and the dispersion relations at general points of the Brillouin zone have been derived by group-theoretical methods. From an analysis of the experimental and theoretical data conceivable energy band models of the tetragonal ZnP2 and CdP2 crystals are proposed.
