Abstract
The passivation of deep acceptor level defects (Ev +0.33 eV, Ev +0.19 eV) associated with copper in single-crystal germanium by reaction with atomic hydrogen has been observed using deep level transient spectroscopy. The concentration profile of the Ev +0.33 eV center is presented as a function of the duration and temperature of the exposure to atomic hydrogen—when exposed for 3 h at 300 °C, 90% of the acceptor defects were passivated to a depth of ∼80 μm.
