Abstract

It is found that the 1115 and 1157 cm^-1 absorption bands in GaAs doped intentionally with ¹³C (measured at 300 K) are manifestations of the localised vibrational mode two-phonon absorption of ¹²C _As and ¹³C_As. The ratios of the absorption intensity for single-phonon processes to that for two-phonon processes for ¹²C and ¹³C in GaAs are about 87 at 300 K and 75 at 10 K, respectively.
