摘要:

扫描探针方法(隧道和力显微镜,STM和AFM)的同时组合是一种独特的方式来获得有关所研究表面的晶体学和电子结构的信息。在这里,我们应用这些方法伴随着最先进的密度泛函理论(DFT)计算,以阐明强波纹石墨烯/Rh(111)系统的结构和电子性质。原子分辨图像的STM和AFM模式,并与DFT的结果显示良好的理论和实验之间的协议。

英文摘要:

The simultaneous combination of scanning probe methods (tunnelling and force microscopies, STM and AFM) is a unique way to get an information about crystallographic and electronic structure of the studied surface. Here we apply these methods accompanied by the state-of-the-art density functional theory (DFT) calculations to shed a light on the structure and electronic properties of the strongly-corrugated graphene/Rh(111) system. The atomically resolved images are obtained for both STM and AFM modes and compared with the DFT results showing good agreement between theory and experiment.
