Advances of SiOx and Si/SiOx Core-Shell Nanowires | …

Various materials have been synthesized in the form of nanowires, such as silicon, germanium, gallium nitride, gallium arsenide, and silicon carbide (Spanier, 2006). Thus, it is important to understand properties, appliions and synthesis methods of the nanowires so as to be able to produce nanowires with well-controlled properties and dimensions to be incorporated into electronic devices.

Cubic SiC Nanowires: Growth, Characterization and …

Functionalized 3C-silicon carbide NW have the potential to act as highly sensitive detector elements in bio-chemical field (Yakimova et al., 2007). Many methods are currently being used to prepare SiC-NW (pure or with a SiO 2 shell) on silicon substrates using a alyst, including chemical vapour deposition, vacuum evaporation of SiC, direct synthesis from Si and C powders.

A system of Cr 3 C 2 powder and Ni 70 Mn 25 Co 5 alloy in weight ratio of 1:6 was treated under 6.0 GPa and 1 500 C for 20, 30 or 60 min respectively. X-ray diffraction of the samples indied the Cr 3 C 2 decomposed partially after high pressure and temperature treatment, and Cr 7 , C 3 , Cr and diamond formed respectively.

Wide bandgap semiconductors for LEDs, solar and related …

Resume : Energy challenges are dramatically boosting the development of wide band gap semiconductors, such as silicon carbide (SiC). Despite tremendous efforts, homoepitaxial growth of 4H- or 6H-SiC epilayers on on-axis (0001) surfaces by the standard chemical vapour deposition process still faces the difficult problem of two-dimensional nucleation, giving rise to polytype inclusions.

The situation while being similar to silicon or germanium, or diamond, or GaP, or AlP or AlAs, … is different in the sense that both extrema sit at edges of the Brillouin zone. Instead of needing a phonon at the edge of the Brillouin zone, a phonon at its middle (the so-called T point) along the Γ-K direction is needed, according to group-theory considerations [ 41 ], [ 45 ], [ 23 ].

At the surface of the melt, temperatures are usually lower (approximately 1600 C) and reactants are reduced to form silicon carbide (SiC), SiO 2 + 3C → SiC + 2CO (g) (1) In this distillation‑like process, the SiC and SiO 2 descend to the lower, hotter parts of the furnace.
