Comparative Analysis of Photo-Crystallization in a-Se₉₅Te₅ and a-Se₉₅In₅ Alloys

We report a comparative study on photo-crystallization in a-Se₉₅Te₅ and a-Se₉₅In₅ alloys. The photo-crystallization is achieved by a shining white line on the thin films of these alloys in vacuum for different exposure times. The results indicate that photo-crystallization is fast in a-Se₉₅In₅ alloy as compared to a-Se₉₅Te₅ alloy. This is explained in terms of lower thermal stability of a-Se₉₅In₅ alloy as compared to a-Se₉₅Te₅ alloy.
