Abstract

Deep level transient spectroscopy (DLTS) together with first-principles calculations are used to investigate the centers that are formed upon annealing of the dominant VO center in Ge. It is suggested that as opposed to Si, the VO₂ complex in Ge is bistable and a double acceptor, with first and second acceptor levels 0.365 and 0.195 eV below the conduction band, respectively.
