摘要：

We report a reproducible synthetic method for superconducting Cu-intercalated Bi2Se3 by an improved melt growth method. Avoiding the production of Cu2Se, which has a higher melting point than that of Bi2Se3, and quenching CuBi-Se mixtures at the liquid phase are keys to obtaining good superconducting samples in a reproducible manner.
