英文摘要:
The influence of pulse fluences on phase transition dynamics processes of amorphous Ag8In14Sb55Te23 (AgInSbTe) thin films induced by single nanosecond laser pulses were studied by transient optical reflectivity measurements. Phase transition driven by nanosecond laser pulses have been achieved in a proper fluence range on AgInSbTe thin films. It was found that phase transition dynamics induced by nanosecond laser pulses was a multi-stage optical evolution process involving melt, solidification, recalescence, and recrystallion. The dependence of time parameters and normalized reflectivity change determined by optical evolution curve on laser pulse fluence was studied and analyzed. (C) 2015 Elsevier GmbH.
