Superconductivity in S-doped TiSe2
ORAL
Abstract
We have observed superconductivity in resistivity measurements of sulfur-doped TiSe\textunderscore (2-x)S\textunderscore x. We studied the SC phase boundary as a function of S-substitution using X-ray scattering to characterize the charge density wave (CDW) phase in these samples as a function of doping and temperature. A charge density wave peak persists in the highest doped sample studied, at x $=$ 1.09. Our temperature vs. doping phase diagram shows that the SC dome, located at around x $=$ 0.15, is well within the boundary of the charge ordered phase, indicating that the dome is not associated with an amplitude quantum critical point.
