Combining graphene with silicon carbide: synthesis and properties - a review
Being a true two-dimensional crystal, graphene possesses a lot of exotic properties that would enable unique applications. Integration of graphene with inorganic semiconductors, e.g. SiC promotes the birth of a class of hybrid materials which are highly promising for development of novel operations, since they combine the best properties of two counterparts in the frame of one hybrid platform. ...
متن کاملElectronic structure of epitaxial graphene layers on SiC: effect of the substrate.
A strong substrate-graphite bond is found in the first all-carbon layer by density functional theory calculations and x-ray diffraction for few graphene layers grown epitaxially on SiC. This first layer is devoid of graphene electronic properties and acts as a buffer layer. The graphene nature of the film is recovered by the second carbon layer grown on both the (0001) and (0001[over]) 4H-SiC s...
متن کاملGraphene Formation on the Carbon face of Silicon Carbide
In this thesis, we study the structure of epitaxial graphene formed on polar faces of SiC the (0001) face, also known as the Si-face, and the (0001 ) face, known as the C-face. On both polar surfaces, graphene films are prepared in ultra-high vacuum (UHV), in environments either of argon or cryogenically purified neon, or in a low-pressure background of disilane. Characterization of graphene is...
متن کاملChemically resolved interface structure of epitaxial graphene on SiC(0001).
Atomic-layer 2D crystals have unique properties that can be significantly modified through interaction with an underlying support. For epitaxial graphene on SiC(0001), the interface strongly influences the electronic properties of the overlaying graphene. We demonstrate a novel combination of x-ray scattering and spectroscopy for studying the complexities of such a buried interface structure. T...
متن کاملThe effect of doping Graphene Quantum Dots with K, B, N, and Cl on its emitted spectrum
In this work, the effect of doping Graphene Quantum Dots (GQDs) on their emission spectra has been studied. First, graphene has been deposited on SiC substrate by using sublimation method. Second, doped-GQDs have been distributed on the surface of graphene via drop casting. The structure of the samples have been studied and characterized by X-ray diffraction (XRD), Scanning Electron Microscopy ...
