Abstract: We report superconductivity induced in films of the non-superconducting,antiferromagnetic parent material FeTe by low temperature oxygen incorporationin a reversible manner. X-ray absorption shows that oxygen doping changes thenominal Fe valence state from 2+ in the non-superconducting state to mainly 3+in the superconducting state. Thus superconductivity in O doped FeTe occurs ina quite different charge and strain state than the more commonFeTe$ {1-x}$Se$ x$. This work also suggests a convenient path for conductingdoping experiments in-situ with many measurement techniques.
