AbInitio Calculations of the Superconducting Transition Temperature for NbC at Various Pressures.

Abinitio calculations of the superconducting properties have been performed for niobium carbide (NbC) at normal pressure and upon a 15 and 30% compression. Factors accounting for the relatively low values of the transition temperature T_c in transition metal carbides are considered and the possible ways of increasing this parameter are discussed. © 2004 MAIK “Nauka / Interperiodica”.
