We report the phase diagram of infinite layer thin films grown on . A superconducting dome spanning is found, remarkably similar to cuprates, albeit over a narrower doping window. However, while cuprate superconductivity is bounded by an insulator for underdoping and a metal for overdoping, here we observe weakly insulating behavior on either side of the dome. Furthermore, the normal state Hall coefficient is always small and proximate to a continuous zero crossing in doping and in temperature, in contrast to the dependence observed for cuprates. This suggests the presence of both electronlike and holelike bands, consistent with band structure calculations.
