Abstract

Core–shell samples of thin films of tantalum nanoclusters and of tantalum oxides on silicon were obtained. The chemical composition of Ta/TaO2 nanoclusters was determined based on the results of X-ray photoelectron spectroscopic (XPS) analysis. The homogeneity of the thin nanocluster film composition was ascertained by the character of angular dependences of the ratios of the Ta4f doublet and oxygen peaks. The effect of a dimensional shift of binding energy was observed for metal tantalum nanoclusters with the diameter d < 5 nm, and its dependence on the nanocluster diameter was established.

Abstract Image

获得了钽纳米团簇和钽氧化物在硅上的核壳薄膜样品。根据 X 射线光电子能谱(XPS)分析结果确定了 Ta/TaO2 纳米团簇的化学成分。纳米簇薄膜成分的均匀性是通过 Ta4f 双峰和氧峰的角度相关性来确定的。在直径为 d < 5 nm 的金属钽纳米团簇中观察到了结合能的尺寸偏移效应,并确定了其与纳米团簇直径的关系。
