Amorphous Sb₂Te₃ thin films are synthesized using electrodeposition in different thicknesses to explore their solid electrolytic nature with respect to some noble metals. Au and Pt are used as the substrate materials and thermally diffused into the Sb₂Te₃ films under passivated and nonpassivated conditions. Rutherford backscattering spectrometry is used to study the Au and Pt diffusion into the films as a function of depth. It is found that Au diffuses into the Sb₂Te₃ thin films even at room temperature. In contrast, there is no observable diffusion of Pt at room temperature. At a higher temperature (i.e., 200 °C), both Au and Pt diffuse into the Sb₂Te₃ thin films and Au diffusion is more significant than Pt. The findings suggest that amorphous Sb₂Te₃ can be used as a good solid electrolyte to permit the diffusion of some noble metals such as Au and Pt.

电沉积非晶 Sb2Te3 薄膜中的 Au 和 Pt 扩散

使用不同厚度的电沉积合成非晶 Sb ₂ Te ₃薄膜，以探索它们对某些贵金属的固体电解性质。Au和Pt用作衬底材料并在钝化和非钝化条件下热扩散到Sb ₂ Te ₃膜中。卢瑟福背散射光谱法用于研究金和铂扩散到薄膜中作为深度的函数。发现即使在室温下Au也会扩散到Sb ₂ Te ₃薄膜中。相反，在室温下没有观察到 Pt 的扩散。在较高温度（即 200 °C）下，Au 和 Pt 均扩散到 Sb ₂ Te₃薄膜和Au 扩散比Pt 更显着。研究结果表明，无定形 Sb ₂ Te ₃可用作良好的固体电解质，以允许一些贵金属如 Au 和 Pt 的扩散。
