| 内容記述 | In order to investigate the process of oxidizing graphene, the chemical and electronic states have been studied by X-ray absorption fine structure (XAFS) and photoelectron spectroscopy (PES) measurements. Single layer graphene oxide was formed on sapphire(0001). After oxidation until 30s, XAFS results showed a decrease of C pi* intensity and an appearance of O pi* intensity and PES results showed a similar electronic state. However, 45s oxidation leaded to a different electronic state, and the O pi* intensity decreased for 60s oxidation. The oxidation is thought to firstly introduce the oxygen functional groups, then to modify the graphene. | |||||
