Abstract
Optical measurements of semi-insulating GaAs in spectral region 1400 - 500 cm-1 are presented. The new absorption lines X5 (1201.8 cm-1) and X4 (1317.5 cm-1) are observed. It has been found that they are related to electrically active defects and are electronic transitions in nature. The coupling of the defect responsible for these lines with the lattice is stronger than CC model predicts. Our results seems to suggest that the lines are related to VAs defect.
