Abstract
The layered lithium borocarbide LiBC, isovalent with and structurally similar to the superconductor , is an insulator due to the modulation within the hexagonal layers (BC vs ). We show that hole doping of LiBC results in Fermi surfaces of B-C character that couple very strongly to B-C bond stretching modes, precisely the features that lead to superconductivity at in . Comparison of with indicates the former to be a prime candidate for electron-phonon coupled superconductivity at substantially higher temperature than in .
