AbstractCopper monotelluride CuTe has a layered orthorhombic structure (space group Pmmn, No. 59) but exhibits a quasi-one-dimensional charge density wave (CDW) order. Here, we present a high-pressure study of CuTe in a diamond anvil cell at pressures up to 41.8-49.8 GPa, through a combination of electrical transport, synchrotron x-ray diffraction (XRD), and Raman spectroscopy measurements as well as theoretical calculations. Our transport experiments show that the CDW transition is manifested as a hump in resistivity; with the application of external pressure, its transition temperature T-CDW decreases gradually and the amplitude of the resistivity hump decays rapidly. The CDW gets suppressed completely above similar to 10 GPa as estimated by a linear extrapolation of the T-CDW versus P trend. Upon further compression, a sudden drop in resistivity is initially observed at similar to 2.4 K and -20 GPa, and zero resistance is established above similar to 37 GPa, suggesting the occurrence of superconductivity (SC). Combined XRD and Raman data as well as theoretical calculations together evidence that the emergence of SC at similar to 20 GPa is accompanied by an orthorhombic to monoclinic (space group Cm, No. 8) structural transition.
