摘要 | We report the effects of Cu doping on the physical properties of the newly discovered layered superconductor Bi4-xCuxO4S3 (0 <= x <= 0.15). The superconductivity is suppressed gradually with increasing x and finally disappears when x > 0.10. Meanwhile the temperature dependent resistivity changes it slope from positive x < 0.1 to negative x >= 0.1. The lattice constant c decreases initially with x, but increases with increasing x further. However, the lattice constant a (=b) always reduces with x. The suppression of superconductivity and the change of the rho(T) slope may be attributable to a shift of the Fermi energy level due to Cu doping. (c) 2012 Elsevier B.V. All rights reserved. |
