Images were obtained sequentially by first (a) increasing the peak force set point from 1, 2, 5, 7.5, 10 nN followed by (b) reducing the peak force set point from 7.5, 5, 2, 1 nN.
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.
