Abstract:
Helium implantations were realized in polycrystalline tellurium thin films. Discontinuities in the dependence of the relative threshold writing energy with both implanted ion dose and ion beam energy are observed. Correlations between the optical recording properties and the optical loss of the thin films suggest that the intrinsic threshold writting energy of the films is influenced by the implantation process.
