Abstract
Suspended graphene has been studied by STM for the first time. Atomic resolution on mono- and bi-layer graphene samples has been obtained after ridding the graphene surface of contamination via high-temperature annealing. Static local corrugations (ripples) have been observed on both types of structures.
摘要
STM 首次对悬浮石墨烯进行了研究。通过高温退火去除石墨烯表面的污染物后，获得了单原子层和双原子层石墨烯样品的原子分辨率。在这两种结构上都观察到了静态局部波纹（波纹）。
