Abstract:
In this paper, we report a method for chemical doping of graphene with melamine and urea percursors. This is an effective method to intrinsically modify the properties of carbon materials, such as regulating the electronic properties. After scanning survey XPS spectra, the high resolution photoelectron spectra of the most prominent XPS transitions (C1s, O1s, N1s and S2p) are recorded for doped-graphene. Number of layers and the quality of the nitrogen-doped graphene are investigated with transmission electron microscopy (TEM) and Raman spectra.
