Description |
It is known that superconductivity in TlSrLaCuO5 is due to the overlap of empty Tl 6s band with the antibonding Cu 3d(x2-y2) band at the Fermi level. This motivated us to investigate the effects of isovalent-cation substitution in superconducting TlSrLaCuO5 and semiconducting TlBaLaCuO5. We have succeeded in inducing superconductivity in TIBaLaCuO5 by introducing Ca2+ at the Ba sites.
