Paduani Física, Astronomía y Matemáticas 15 FP LAPW Band structure Superconductors The electronic structure of the A15 compounds A3B A=Nb; B=Al,Ga,Ge,Sn and In is studied by means of fullyrelativistic full-potential linearized augmented-plane wave (FP-LAPW) calculations within the formalism of thedensity functional theory. Band structures and densities of states are determined for all the studied compounds.From the calculations are obtained the theoretical lattice constants, the Fermi energy EF , the density of states atthe Fermi level N(EF ) which is used to estimate the electronic specific heat coefficient g and the electron-phononcoupling parameter l for the Nb3In compound. Generally, a good agreement between results of the calculationsand experiments is found. 2007 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46437701 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.3B Vol.37 |
