A reduction in carrier lifetimes by intentional boron (B) doping during epitaxial growth has been previously reported, but the related capture mechanism through B-related defects is not yet fully understood. In this work, deep levels related to B and related carrier capture/recombination mechanisms were investigated using deep level transient spectroscopy (DLTS), minority carrier transient spectroscopy (MCTS) and photoluminescence (PL) measurements.
