Step like surface potential on few layered graphene oxide

(author unknown)



M. Jaafar, G. López-Polín, and C. Gómez-Navarro et al.

We report surface potential maps of few layered graphene oxide films on different substrates. Kelvin probe force microscopy images reveal that the surface potential decreases in steps with increasing number of layers on the substrate until five layers are reached, where it saturates to a constant ...
