Al-implanted Ge samples were investigated by micro-Raman spectroscopy combined with a small angle beveling technique. By means of a reverse Monte Carlo procedure, the concentration profiles of the electrically active dopant ions were determined from the Raman peak observed at 370 cm1 related to substitutional Al atoms. Furthermore, a clear relationship between the Ge–Ge Raman peak at 300 cm1 and the active dopant concentration was also observed. This work shows that micro-Raman spectroscopy could be adopted for quantitative characterizations of the carrier concentration profiles in extrinsic semiconductors.

Abstract: | Al-implanted Ge samples were investigated by micro-Raman spectroscopy combined with a small angle beveling technique. By means of a reverse Monte Carlo procedure, the concentration profiles of the electrically active dopant ions were determined from the Raman peak observed at 370 cm1 related to substitutional Al atoms. Furthermore, a clear relationship between the Ge–Ge Raman peak at 300 cm1 and the active dopant concentration was also observed. This work shows that micro-Raman spectroscopy could be adopted for quantitative characterizations of the carrier concentration profiles in extrinsic semiconductors. |
