摘要
We have performed first-principles, full-potential linear muffin-tin-orbital (FPLMTO) calculations to study the structural phase transition in CdTe under pressure. By calculating the total energies of different phases we have shown that CdTe shows the following structural sequence with increasing pressure; zinc-blende --> cinnabar --> NaCl --> orthorhombic structure. This is in complete agreement with recent experiments. We have also looked for the possibility of an additional phase transition from the orthorhombic to the CsCl structure, which has been anticipated for the isoelectronic compound HgTe in recent experiments.
