Graphene Analysis with Atomic Force Microscope (AFM)

In Fig. 1, we present typical AFM images of graphene deposited on mica at ambient conditions [room temperature; relative humidity (RH) ~ 40%].In agreement with a recent study (), we found that graphene sheets spread atomically flat on mica over areas of 100 to 200 nm on a side (fig. S6).Over larger areas, however, islandlike plateaus varying from a couple nanometers to a few micrometers in.
