Silicon carbide SiC is a compound mainly formed by the covalent bond between silicon (Si) and carbon (C). Its basic unit is siC tetredron, in which Si atom is located in the center and C atom is around. All structures of SiC consist of SiC tetredrons piled up in different ways. Now have found the silicon carbide homogeneity of different crystal structure has more than 200, including the

An investigation was conducted to explore the mechanisms of the scratching of monocrystalline silicon carbide with a single diamond grit. The scratching was repeated on a silicon carbide workpiece to generate different wear shapes of the diamond grit. The forces were recorded during each scratching and the wear of the diamond grit together with the silicon carbide morphologies was monitored at a

Graphene (/ ˈ ɡ r æ f iː n /) is an allotrope of carbon consisting of a single layer of atoms arranged in a twodimensional honeycomb lattice. The name is a portmanteau of "graphite" and the suffix ene, reflecting the fact that the graphite allotrope of carbon consists of stacked graphene layers.. Each atom in a graphene sheet is connected to its three nearest neighbors by a σbond, and
