TeO_x-Au薄膜の結晶化に及ぼすAuの添加効果

概要

論文の詳細を見る
The effect of Au addition on crystallization was investigated for TeO_x-Au films used for optical recording materials. Crystallization phases precipitated from the films were found to be AuTe_2 in low Au content films and AuTe_<1.7> in high Au content films. The crystallization rate was much faster in the case of crystalline AuTe_<1.7> than in the case of crystalline AuTe_2. The time required for the signal saturation due to the crystallization of the films irradiated by laser (850 nm in wavelength, 8 m W/um^2 in power) was shortened up to 60 ms for the films in which AuTeh_<1.7> was precipitated from 30 s for the pure TeO_x films in which crystalline Te was precipitated. The transformation mechanism from the amorphous to the crystalline state in these films is discussed.
