扫描探针方法（隧道显微镜和力显微镜、STM 和 AFM）的同时组合是获取有关所研究表面的晶体学和电子结构信息的独特方法。在这里，我们应用这些方法以及最先进的密度泛函理论（DFT）计算来揭示强波纹石墨烯/Rh（111）系统的结构和电子特性。在 STM 和 AFM 模式下都获得了原子分辨图像，并将其与 DFT 结果进行比较，显示理论与实验之间具有良好的一致性。
The simultaneous combination of scanning probe methods (tunneling and force microscopies, STM and AFM) is a unique way to get 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.
