Abstract
Local-density-approximation electronic-structure calculations for the recently discovered LaPt2B2C superconductor are reported. The calculations show, as in LuNi2B2C, that despite the quasi-two-dimensional crystal structure, the electronic structure in the vicinity of the Fermi energy (EF) is quite three dimensional, with substantial contributions from all atoms. In this compound, EF falls on the low-energy side of a peak in the electronic density of states, suggesting that Tc may be increased by doping to a higher electron count. The value of the density of states at EF is found to be substantially smaller than that of LuNi2B2C in agreement with experiment.
