Reproducible synthetic method for the topological superconductor
CuxBi2Se3 [PDF]
Ryusuke Kondo, Taiki Yoshinaka, Yoshinori Imai, Atsutaka MaedaWe 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.View original: http://arxiv.org/abs/1303.3786
