Effect of energetic ion irradiation on CdI2 films

The effect of plasma irradiation is studied systematically on a 4H polytype (002) oriented

Laser-induced crystallization in amorphous films of (C = S, Se, Te), potential optical storage media

stoichiometric film having compressive residual stress. Plasma irradiation was found to change the orientation to (110) of the film at certain moderate irradiation distances. A linear decrease in grain size and residual stress was observed with decreasing irradiation distance (or increasing ion energy) consistent with both structural and morphological observations. The direct optical energy gap
