Abstract
An EPR spectrum, labeled Si-G29, is identified as a lattice vacancy trapped by substitutional tin. The resulting tin-vacancy pair is observed in its neutral ground state with . Studies versus wavelength of illumination indicate that it has a donor level at eV. Analysis of the EPR spectrum leads to a model in which the tin atom resides in a position halfway between two normal silicon atom sites (). It is stable to ∼500 K.
