Paper Abstract

Reported here are the experimental results about Ni-doped Sb2Se3 phase change recording thin films prepared by DC & RF magnetron co-sputtering. It is found that doping a small percentage of nickel (Ni) into Sb2Se3 thin films have the effect to increase the films recording sensitivity and decrease the polycrystalline grain size about one order of magnitude after 8.9 at% of Ni is doped. The sample's static test for erasable optical recording shows that using 20 mW, 200 ns, or 15 mW, 200 ns laser pulses, a recoding bit can be written or erased on the film, thus Ni-doped Sb2Se3 media have the potential for practical rewritable recording.
