AFM image and height profiles of exfoliated graphene sheets using LPE

AFM images of graphene oxide sheets laying over a Si/SiO 2 substrate

Previous studies using AFM analysis have shown that the thickness of monolayer graphene nanosheets, and the inter-layer spacing are about 0.57 nm, and 0.6-0.7 nm, respectively.

AFM image and height profiles of exfoliated graphene sheets using LPE

Atomic force microscopy (AFM) is utilized in determining the surface structure and thickness of graphene [84]. An AFM generates images by scanning a small cantilever over the surface of a sample. The sharp nanoscale tip at the end of the cantilever contacts the surface, thus bending the cantilever and changes the amount of laser light reflected.

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.

Typical AFM image of graphene oxide sheets and corresponding height

The atomic force microscopy (AFM) is a direct and visual analytical method to examine the topographical and cross-sectional features of graphene materials. In this study, AFM was carried out, in parallel to HR-TEM, to determine the number of GO layers. Fig. 4 shows the AFM images of GO sheets exfoliated in different polar solvents. In general.
