This paper aims to study the amorphous-to-crystalline phase transition characteristics of novel optical phase change material: Ge2Sb2Se4Te1 using excitation wavelength situated in the low absorption window of the phase change material. The GSST thin film is 300 nm thick and is coated on a glass subs...
