A photoluminescence investigation of local mode vibrations of the beryllium pair centre in silicon

Year: 1990

Type: article

Abstract: A detailed examination of the spectrum of the isoelectronic bound exciton (IBE) recombination attributed to Be pair centres in Si reveals the presence in the sidebands of a previously unreported sharp local mode phonon of energy 104.7+or-0.5 meV (844+or-4 cm -1 ). The energy of this local vibrational mode is in excellent agreement with a recent prediction of 860 cm -1 for the vibrational energy of a pair of Be atoms aligned along a (111) crystal direction where one of the atoms occupies a substitutional site and the other an adjacent tetrahedral interstitial site. This result provides the most convincing evidence to date for assigning the IBE spectrum to Be pair centres with this configuration.
