摘要：
We have studied the Raman spectra of initially amorphous hydrogenated silicon (a-Si:H) films upon their exposure to femtosecond laser-radiation pulses with the fluence varied within 30–155 mJ/cm2. The distribution of the volume fraction of a crystalline phase over the surface of processed films is determined for the first time and a correlation is established between changes in this value and the hydrogen content in a-Si:H films upon the crystallization induced by femtosecond laser radiation.
