Abstract

Tetrahedrally coordinated binary II–VI semiconductors are reported to crystallize both in cubic zinc-blende and hexagonal wurtzite structures. The relative stability of these structures and its origin have caught the attention of several researchers in the past. In this work, we revisit this issue for the CdX (X = S, Se, Te) series employing the Nth-order muffin-tin orbital technique. Our study correctly brings out the trend in this series, providing useful insight in terms of constructed Wannier functions.
