Diamond crystals with a facet size exceeding the size of the focus of the X-ray beam incident on the sample were synthesized by the HPHT method were heated to a temperature of 850 °C and 1250 °C for 15 minutes. Annealing of samples of single crystals was carried out in a high-vacuum chamber of the Russian-German laboratory at the BESSY II synchrotron source. XPS spectroscopy was used to study the structure of carbon layers on diamond faces of different symmetries and with thin layers of iron and nickel deposited on a diamond. A higher rate of graphitization of the (111) face is shown. From the data of the angular dependence of NEXAFS, the directionality of the sp2 carbon layers relative to the diamond surface is determined. The data obtained indicate a catalytic effect of the metal on the process of the formation of graphene structures. Transmission electron microscopy data demonstrate the characteristic size and misorientation of individual graphene layers for different symmetry of diamond faces.
