| Evolution of the Electronic Structure of 1T-CuxTiSe2 (2006) | |||||||||
Abstract | |||||||||
| The electronic structure of a new charge-density-wave/ superconductor system, 1T-CuxTiSe2, has been studied by photoemission spectroscopy. A correlated semiconductor band structure is revealed for the undoped case. With Cu doping, the charge density wave is suppressed by the raising of the chemical potential, while the superconductivity is enhanced by the enhancement of the density of states. Moreover, the strong scattering at high doping might be responsible for the suppression of superconductivity in that regime.. Comment: 5 pages, 4 figures | |||||||||
