Energy band structure of Cd₃P₂ for real D symmetry II. Symmetry properties

Abstract

The fundamental symmetry properties of the D 4h15 space group, necessary in determining the band structure of Cd3P2 are studied in detail. The SCPW for all points and axes of high symmetry, and the compatibility relations for this group are constructed. The selection rules for double‐valued representations are calculated. Finally, the consequences of including spin to the calculated band structure of Cd2P2 are discussed.

Phase transitions in Cd3P2 at high pressures and high temperatures

“…Plenkiewicz and Dowgiallo-Plenkiewicz [12,13] have carried out further studies on the band structure and symmetry operations of Cd 3 P 2 in the real-crystal symmetry. They used a pseudo potential method, in which a qualitative explanation of the band structure and the optical properties could be made.…”
