23/6/2009· With the aid of the new TB model, minima of silicon carbide cagelike clusters, nanotubes, ring-shaped ribbons, and nanowires are predicted. Energetics, structure, growth sequences, and stability patterns are reported for the nanoclusters and nanotubes.
Silicon carbide (SiC) is a promising material due to its unique property to adopt different crystalline polytypes which monitor the band gap and the electronic and optical properties. Despite being an indirect band gap semiconductor, SiC is used in several high-performance electronic and optical devices. SiC has been long recognized as one of the best biocompatible materials, especially in
Silicon Carbide Oxidation Most wide bandgap materials are difficult to oxidize thermally. Luckily, SiC is an exception, which can be oxidized into SiO 2 thermally. This enables us to borrow the Si oxidation processes and adapt them for SiC oxidation. Despite the

Advanced Inorganic Materials for Solid State Lighting In 1907, the first electroluminescent device, with silicon carbide (Prod. Nos. 594911, 378097, 357391) as the active material, was described by Henry Round as displaying a “bright glow”.1,2 Lighting
Published data on silicon carbide nanotubes (SiC-NT) are analyzed. According to theoretical calculations, single-layer SiC-NTs do not dissociate, but they have not yet been detected experimentally. According to the experimental data, metastable SiC-NTs with walls consisting of several layers and nanotube fibers were produced. The optimized structure of single-layer SiC-NTs was calculated by

Silicon carbide nanotubes (SiCNTs) were directly synthesized by chemical vapor deposition (CVD) in the paper. Methyltrichlorosilane (MTS) was selected as the SiC gaseous source and, ferrocence and thiophene as the alyst and the coalyst, respectively.
Initially, studying thermal decomposition of solids was for the purpose of examining thermal stability of materials. With the discovery of epitaxial growth of graphene and self-aligned CNTs on the crystal surfaces of silicon carbide, thermal decomposition has developed into a facile method of producing alyst-free, high-purity, and highly homogeneous carbon.
