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.
