Abstract

We report on a scanning tunneling microscopy (STM) study of the nanostructuring of the Au/Ru(0001) thin film system for the cases of 5 monolayers (ML) and 9 ML of Au deposited at 300 K and subsequently annealed at 1050 K. A new laterally periodic superstructure is observed at the surface of the 9 ML film, which is essentially a rippling in height of the surface atomic layer with the magnitude up to 0.03 ± 0.01 nm and in-plane periodicity of 4.6 ± 0.4 nm, the long-range order being absent.

摘要

我们报告了一项关于Au/Ru(0001)薄膜系统纳米结构的扫描隧道显微镜（STM）研究，该研究针对在300 K下沉积5个单层（ML）和9个ML的Au，随后在1050 K下退火的情况。在9个ML薄膜的表面观察到一种新的横向周期性超结构，它本质上是表面原子层高度的起伏，幅度高达0.03±0.01 nm，面内周期性为4.6±0.4 nm，不存在长程有序。
