Abstract: Heavily boron-doped silicon films grown by molecular beam epitaxy are investigated by Raman scattering. The lineshapes of Raman spectra are analyzed based on the theory of electron-phonon interaction. The relation between the linewidth and the carrier concentration is established experimentally,and the resul is consistent with the theoretical estimation found in previous literature.The relation provides a calibration for determining the carrier concentration through Raman scattering measurements.

Key words: Raman spectra, heavily boron-doped, electron-phonon interaction
