2D triangular β‐Cu 2 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 2 S to γ‐Cu 2 S occurs at 258 K (−15 °C), and such transition temperature is 120 K lower than that of its bulk counterpart (about 378 K).
