Research Abstract

In this study we aimed to observe lattice dynamics in femto- to pico-second time scales during the crystalline-amorphous phase change in chalcogenide alloy (Ge-Sb-Te mixed crystals), which is extremely important materials for optical recording media. As the results, we could observe ultrafast (< 1 ps) phase change by exciting with double-pulse (pulse-pair). The pump-polarization dependent phase change phenomena have also been found in the pump-probe experiment.
