Growth Mechanism of Cubic-Silicon Carbide Nanowires
Cubic-SiC nanowires were synthesized using activated carbon powder and Si substrate in vacuum at 1200–1350°C for 1–4 hours. The nanowires were grown according to the following proposed mechanisms: (1) diffusion of C/CO into Si substrate, (2) weakening of Si bond and atomic kick-out, (3) formation of Si-C in vapor phase, (4) formation of saturated SiC layer, (5) formation of pyramid-like

Aluminum-Silicon Alloys - Materials Database
Aluminum-silicon alloys without copper have good corrosion resistance in most reagents; only in alkaline solutions which attack silicon as well as aluminum their performance is poor. Copper reduces appreciably the corrosion resistance and so does iron, unless corrected with manganese or chromium.

They either have an extended three-dimensional covalent network-lattice structure, as exemplified by diamond (carbon) and silicon dioxide (sand), SiO 2, and silicon, Si. Or they present as discrete molecules like fluorine, F 2 , methane, CH 4 , or glucose, C 6 H 12 O 6 that interact with each other via weak (van der Waals/dipole-dipole/hydrogen bonding) forces.
PCIM: First trench SiC mosfet is 2x better
Trench structures will halve the on-resistance of silicon carbide power mosfets, claimed Rohm. “Compared to existing planar-type SiC mosfets, on-resistance is reduced by 50% in the same chip size, making it possible to significantly decrease power loss,” said the firm.

2013/10/1· Nevertheless, the structure can be considered to be a new amorphous phase with a high concentration of mixed-bond tetrahedra and not an intergrowth of separate silicon carbide and silicon oxide nanophases. The absence of carbon-oxygen bonds in these 2.
High withstand voltage (reverse voltage) characteristics of SiC …
Silicon carbide (SiC) is a wide-bandgap semiconductor with a bandgap of 3.26 eV, much higher than that of silicon (Si) (=1.12 eV). SiC provides high electric breakdown field and high thermal conductivity because of high atomic bond due to a low lattice constant (i
Property Modifiion - Alloying - Phase Diagrams
When an alloy exhibits more than two phases, a different type of phase diagram must be used, such as a ternary diagram for three phase alloys. This discussion will focus on the binary phase diagram. On the binary phase diagram, compositions run from 100% Element A on the left, through all possible mixtures, to 100% Element B on the right.

Using first-principles methods we performed a theoretical study of carbon clusters in silicon carbide (SiC) nanowires. We examined small clusters with carbon interstitials and antisites in hydrogen-passivated SiC nanowires growth along the  and  directions. The formation energies of these clusters were calculated as a function of the carbon concentration. We verified that the
Phase Diagram - Industrial Metallurgists
Under these conditions it is possible to have phases missing or present compared to what is indied by the phase diagram. Therefore, it is also important to understand the kinetics of phase transformations, i.e. the effects of temperature, time, cooling rate, and heating rate on phase changes within an alloy.
