Coexistence of polar structural character and superconductivity in pressurized CuInP2Se6 single crystal
Pressurization is a common method for regulating the crystal structure and physical properties of materials without altering their chemical composition. In this work, the two-dimensional (2D) CuInP2Se6 single crystal was prepared using a P2Se5 reactive-flux method. The pressure-driven phase transition and evolution o...
