Abstract

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 Cu- Bi-Se mixtures at the liquid phase are keys to obtaining good superconducting samples in a reproducible manner.
