Diamond surface is stability in atmospheric condition. It is well known that chemical treatment of a diamond surface by sulfuric or nitric acid adds oxygen atoms to the surface. In this study, we examined single-crystal and polycrystalline diamond powder, boiled in sulfuric or nitric acid then heated in ultra-high vacuum (UHV). Analysis of the surface state was carried out by X-ray photoelectron spectroscopy (XPS). The single-crystal diamond powder presented various oxygen states, such as alcohol and ether. Moreover, it was revealed than binding state of diamond surface which oxygen was sublimated by heat treatment in UHV condition was changed. On the other hand, the binding state of the polycrystalline diamond powder did not change from the initial ether combination.
