“…In this paper we demonstrate the growth of graphene layers using diamond (001) oriented substrate as a source for carbon in a PUC process. We prove that the catalytic reaction of nickel on diamond [27,29,30,31] enables the use of diamond as a carbon solid source for the fabrication of thin multilayer graphene films (see figure 1). Furthermore, we show that it is possible to combine this method with a Molecular Beam Deposition (MBD) [23] of carbon to enhance the quality of the graphene layers.…”

Multilayer graphene is grown by precipitation upon cooling of a thin nickel film deposited by e-beam evaporation on single crystal diamond (001) oriented substrates. Nickel acts as a strong catalyst inducing the dissolution of carbon from diamond into the metal. Carbon segregation produces multilayers of graphene on the top surface. Characterization by Raman spectroscopy reveals that these thin layers display relatively narrow Raman phonon peaks that are typically associated with graphene. Atomic force microscope measurements reveal a multigrain structure that reproduces small domains in the nickel film. The multilayer graphene is transferred onto a optical microscope glass slide for further analysis. The thickness of the layers estimated from optical transmission measurements is 12 nm. The catalytic reaction found for nickel on diamond is not observed when glassy carbon is used as substrate. This method provides a venue for the fabrication of large area graphene films.

“…Graphitization on a bare monocrystalline diamond C(111) surface began at approximately 850 °C, 13 while for a bare monocrystalline diamond surface C(100) graphitization began at 1200 °C. 14 Monocrystalline diamond substrates with a large surface area for graphene-on-diamond technology would be too costly for commercial applications. However, nanocrystalline diamond (NCD) offers an alternative, chemically matched native platform for graphene synthesis.…”

“…Metals such as Ni, Cu, or Fe are used to melt or dissolve carbon atoms − and, therefore, to reduce the graphitization temperature of a diamond surface significantly. In particular, a graphitization temperature as low as 247 °C has been reported on Ni/C(100) …”

Study of Ni-Catalyzed Graphitization Process of Diamond by in Situ X-ray Photoelectron Spectroscopy

et al. 2018

Graphene on diamond has been attracting considerable attention due to the unique and highly beneficial features of this heterostructure for a range of electronic applications. Here, ultrahigh-vacuum X-ray photoelectron spectroscopy is used for in situ analysis of the temperature dependence of the Ni-assisted thermally induced graphitization process of intrinsic nanocrystalline diamond thin films (65 nm thickness, 50–80 nm grain size) on silicon wafer substrates. Three major stages of diamond film transformation are determined from XPS during the thermal annealing in the temperature range from 300 °C to 800 °C. Heating from 300 °C causes removal of oxygen; formation of the disordered carbon phase is observed at 400 °C; the disordered carbon progressively transforms to graphitic phase whereas the diamond phase disappears from the surface from 500 °C. In the well-controllable temperature regime between 600 °C and 700 °C, the nanocrystalline diamond thin film is mainly preserved, while graphitic layers form on the surface as the predominant carbon phase. Moreover, the graphitization is facilitated by a disordered carbon interlayer that inherently forms between diamond and graphitic layers by Ni catalyst. Thus, the process results in formation of a multilayer heterostructure on silicon substrate.

“…1(4), it is considered that the treatment would etch the Ni layer as well as diamond as reported previously. 25) As for our experiments, we could obtain the data on the Ni layer behavior after thermochemical-etching for the case of annealing at 800°C, which was estimated from surface profiles measured with a laser profiler before/after the Ni layer removal. As a result, it was found that the Ni layer thickness after thermochemical-etching was estimated to be about 0.8 « 0.1¯m, which was approximately 20 % thinner than that before the thermochemical-etching.…”

We examined the influence of diamond-etching conditions on microneedles fabricated by a thermochemical reaction between a Ni film with pinholes and a diamond (100) wafer in an H 2 atmosphere. The diamond microneedles fabricated by varying the annealing temperatures and thickness of the Ni film coated on the diamond were characterized by scanning electron microscopy. Relatively uniform and long diamond microneedles, with diameters of about 1¯m and heights of about 20¯m, were obtained by annealing for 6 h at 850°C. For Ni films thicker than 1¯m, microneedles with inverted conical shape were obtained, whereas those fabricated with thinner Ni films exhibited a conical shape.
