Superconductivity in electron-doped \emph{Ln}OBiS$_2$ Compounds*

We present observations of superconductivity in electron-doped \emph{Ln}OBiS$_2$ compounds (\emph{Ln} = La, Ce, Pr, Nd, Yb). Polycrystalline samples were synthesized by a two step solid-state reaction and characterized by x-ray diffraction. The parent compounds, \emph{Ln}OBiS$_2$, exhibit a non-metallic ground state. Superconductivity with $T_c$ in the range 1.9 K - 5.4 K was induced by electron doping these compounds via the substitution of F for O. Prior to the onset of superconductivity, the electrical resistivity of the electron-doped \emph{Ln}OBiS$_2$ compounds exhibit semiconductor like behavior, similar to the behavior observed in the parent compounds.
