Ab-initio calculations1 for K3C60 indicate that the general features of the energy bands within LDA remain nearly unchanged as compared to C60. In the electronphonon pairing mechanism of superconductivity in these materials, the variation in Tc has been attributed to changes in the lattice constant2 which affects N(EF). We have therefore fitted the valence and conduction bands of the fcc C60, obtained by Troullier and Martins3 from an LDA plane wave basis calculations, with a tight binding model and studied the energy bands as a function of the lattice constant. As the overlap between orbitals on neighbouring balls is small, the band width is found to decrease by about 30% in going from K3C60 to Rb2CsC60. The density of states, thus, obtained is used to estimate variation in Tc from McMillan’s formula. These results are in good agreement with experimental data. Calculations of the energy bands are also presented for the low temperature [Formula: see text] structure.

Electronic Energy Bands

An interaction between soft bond-bending phonon modes and localized 3d – 2p electrons is considered. Its strength is estimated to be of the order of 1 eV/Å. By means of the tight-binding model, the electronic energy bands of La 2 CuO 4 are calculated. It is explicitly shown that a tetragonal to orthorhombic transition does not open a gap at the Fermi energy.
