Abstract
Infrared absorption of as-grown, heat-treated and electron irradiated Ge crystals enriched with either O-16 or O-18 oxygen isotopes has been studied. Vibrational absorption bands at 780, 818 and 857 cm(-1) (741, 776 and 811 cm(-1)) are assigned to di-oxygen complexes (dimers) in Ge: O-16 (O-18). This assignment is based on an analysis of positions and isotopic shifts of the lines as well as on an investigation of dependencies of line intensities on heat-treatment temperature and oxygen content in the crystals. It is argued that there are two configurations of oxygen dimers in Ge, the bands at 780 and 818 cm(-1) being related to one of them and the band at 857 cm(-1) to another. The binding energy of the dimer giving rise to the bands at... (More)

The binding energy of the dimer giving rise to the bands at 780 and 818 cm(-1) is estimated to be about 0.35-0.4 eV. (Less)
