Description
We report on optical and electrical properties of oxygen-vacancy (VO) related defects in cobalt-doped ZnO materials grown using molecular beam epitaxy (MBE). We probe the concentration of the VO in samples with various cobalt contents, which were annealed under different conditions, and correlate it to the magnetic properties of the samples. Our results suggest that the oxygen vacancy is a major player in the observed ferromagnetism of Co-doped ZnO.
