Abstract

1 min read

We have obtained for the first time atomic resolution STM images of free-standing graphene, and have found UHV high temperature annealing conditions to controllably achieve atomically clean surfaces. This is an important premise for fundamental studies of the interaction of pristine graphene with foreign atom species, in particular metals.
