Abstract
GeTe-Sb2Te3-Sb pseudo ternary components alloy shows laser induced rapid crystallization and amorphous change phenomena. Films of non stoichiometric GeTe-Sb2Te3-Sb can be crystallized using laser pulses less than 100ns duration. The crystalline structure shows the cubic structure. The time it takes to laser crystallize varies Sb concentration. And increasing the Sb concentration leads to increased crystallization temperature. The crystallization temperature of 180 C and more than 1200h stable of acceleration test of 80C 80% RH environment. Thin film disk structure of 20nm active layer produce more than million cycle over-write BER(bit error rate) stability. I would like to discuss the degradation model of pinhole generation in phase change disk media.
