Abstract
For 40 years it has been deduced that the presence of Boron and Oxygen in silicon causes the formation of a non-radiative recombination centre, without any consensus as to its exact nature. Here we report the observation, using deep level transient spectroscopy and photoluminescence of the conversion of a deep boron-di-oxygen-related donor trapping state into a shallow acceptor under the action of light or injected carriers. Using ab initio modelling, we propose structures of the B-O2 defect which match the experimental findings. Implications of the presence of this defect, particularly on its deep donor (carrier trapping) configuration, on silicon photodetectors is discussed.
