Abstract
2D triangular β-Cu<sub>2</sub> S nanosheets with large size and high quality are synthesized by a novel method of super-cooling chemical-vapor-deposition. The phase transition of this 2D material from β-Cu<sub>2</sub> S to γ-Cu<sub>2</sub> S occurs at 258 K (-15 °C), and such transition temperature is 120 K lower than that of its bulk counterpart (about 378 K).
