Optical characterization of the oxygen dimer in silicon has been performed for the first time. The vibrational IR absorption bands at 1012, 1060, and 1105 cm(-1) are shown to arise from this complex. Using heat-treatment studies, the dimer binding energy is determined to be about 0.3 eV. Indications of the high migration ability of the dimer predicted earlier are found as well.
