本文报道了一种可重复的Cu插层Bi_2Se_3超导材料的合成方法。避免产生熔点高于Bi 2Se 3的Cu 2Se，并在液相下淬火Cu-Bi-Se混合物是以可再现的方式获得良好超导样品的关键。
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.
