| Summary: | 碩士 === 國立成功大學 === 物理學系碩博士班 === 100 === The core-level electronic structure of exfoliated graphene sheets on a Au-coated SiOx substrate have been studied by using synchrotron radiation photoelectron spectroscopy (SR-PES) on a micro-scale. We firstly demonstrated the visibility of graphene on the Au-coated SiOx substrate by micro-optical characterization, and determined the number of graphene layers by micro-Raman spectroscopy. Because of the elimination of charging effect, precise C 1s core-level characterization revealed different levels of Au-coating-induced p-type doping on single- and double-layer graphene sheets. Moreover, the bonding structures of nitrogen-plasma treated graphene were determined using C 1s and N 1s core-level spectra.
