Fourier-transform infrared-absorption studies of intracenter transitions in the EL2 level in semi-insulating bulk GaAs grown with the liquid-encapsulated Czochralski technique

Abstract

The intracenter transitions that are responsible for the characteristic absorption band of EL 2 in the spectral region of 8060 – 10?0 cm - 1 were studied using a high-resolution Fourier-transform infrared spectrophotometer. The results show that the zero-phonon line observed at 8379 cm - 1 has a complex structure and therefore cannot be assigned to a unique center. The phonon replicas associated with the zero-phonon line indicate that couplings other than transverse acoustic phonon may exist. A group-theoretical analysis of the present results shows that the EL 2 center has a symmetry lower than that of T d suggesting that EL 2 can be identified as a pair defect which involves an arsenic antisite with a vacancy or interstitial.
