The structural, elastic properties and band structures of LiBeN and zinc-blende BN were studied using the full potential augmented plane wave plus local orbitals method within density functional theory. The conduction band modifications of LiBeN, compared to its zinc-blende analog BN, were discussed. For both BN and LiBeN, the valence band top is at the I- point. For BN and alpha-LiBeN (Li+ near the anion), the conduction band minimum is at the X point. The beta-LiBeN (Li+ near the cation) has the conduction band minimum at the L point, due to the increase (decrease) of conduction band bottom energy at X (L) point, relative to I- point. The band gaps of LiBeN decrease compared to BN. The total energy calculations show the alpha phase to be more stable than the beta phase for LiBeN. (c) 2007 Elsevier B.V.

The calculated structural parameters are in good agreement with the available experimental and theoretical data. The elastic constants and their pressure dependences of 'half-Heusler' cubic CoVSb are calculated using the static finite strain technique, and are presented for the first time together with the theoretical pressure-induced phase transition. The research of phase transition and the calculations of electronic structures show that the 'half-Heusler' cubic CoVSb transforms to normal hexagonal CoVSb with atomic configurations I and II at about 13.5 and 78.0 GPa, respectively at OK. Combining the analysis of ground-state structures, it is concluded that the 'half-Heusler' cubic CoVSb mainly transforms to hexagonal CoVSb with atomic configuration I at a relative lower pressure.
