Characterizing the charge order in modulated superconductors provides essential information that could reveal a common underlying mechanism. We performed low temperature experiments on 1T-TiSe 2 crystals tuned by three parameters: pressure, copper intercalation, and sulfur substitution. Resistivity measurements revealed a previously unreported superconductive phase in sulfur substituted samples.
