英文摘要:
The crystallization process of Cr-doped Sb2Te thin films induced by repeated femtosecond laser pulses was studied systematically. The threshold effects and corresponding mechanism were comprehensively analyzed by real-time reflectivity measurements, optical microscopic imaging, and Raman scattering spectra. It was found that by doping the appropriate content of Cr into Sb2Te thin films, improved optical-thermal properties could be obtained, even in ultrafast crystallization processes.
