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 13CAs. 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.
