Crystal growth and characterization of Fe${}_{1+\delta }$Se${}_{1-x}$Te${}_x$ (0.5 $\le$ $x$ $\le$ 1) from LiCl/KCl flux

Qiaoyu Wang, Kexin Bi, Lewei Chen +9

An eutectic LiCl/KCl flux method in a horizontal configuration has been used to grow a series of homogeneous Fe${}_{1+\delta }$Se${}_{1-x}$Te${}_x$ single crystals of high quality with 0.5 $\l…
