摘要

Infrared absorption of as-grown, heat-treated and electron irradiated Ge crystals enriched with either ~(16)O or ~(18)O 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:~(16)O (~(18)O). 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 780 and 818 cm~(-1) is estimated to be about 0.35-0.4 eV.
