The band structure of hexagonal diborides ZrB2, VB2, NbB2 and TaB2 in comparison with the superconducting MgB2
arXiv:cond-mat/0109445
Abstract
The band structure and the Fermi surface of hexagonal diborides ZrB2, VB2, NbB2, TaB2 have been studied by the self-consistent full-potential LMTO method and compared with those for the isostructural superconductor MgB2. Factors responsible for the superconducting properties of AlB2-like diborides are analyzed, and the results obtained are compared with previous calculations and available experimental data.
