• A complete Co doping range up to its solid solubility limit in FeSe have been successfully grown. • The typical lateral size of Fe 1-x Co x Se single crystals is 1–5 mm. • All the samples show metalic behaviour in contrast to a metal insulator transition of Cu doped FeSe. A series of tetragonal Fe 1-x Co x Se single crystals with a complete Co doping range (0 ≤ x ≤ 0.52) up to its solid solubility limit in FeSe have been grown by an eutectic AlCl 3 /KCl molten salt method. The typical lateral size of as-grown Fe 1-x Co x Se single crystals is 1–5 mm. The chemical composition and homogeneity of the crystals was examined by both inductively coupled plasma atomic emission spectroscopy and energy dispersive spectrometer. X-ray diffraction analysis demonstrates that the crystal lattice parameters a and c are both linearly decreased with increasing Co doping level x. In the whole doping range, all the samples show metallic behaviour in contrast to a metal insulator transition of Cu-doped FeSe according to the resistivity measurements. [ABSTRACT FROM AUTHOR]
