Abstract/OtherAbstract:
We report measurements of thermal expansion on a number of polycrystalline Cu(x)TiSe(2) samples corresponding to the parts of x-T phase diagram with different ground states, as well as the pressure dependence of the superconducting transition temperature, T(c), for samples with three different values of Cu doping. Thermal expansion data suggest that the x-T phase diagram may be more complex than initially reported. T(c) data at elevated pressure can be scaled to the ambient pressure Cu(x)TiSe(2) phase diagram; however, significantly different scaling factors are needed to accommodate the literature data on the charge density wave transition suppression under pressure.
