1200V Silicon IGBT vs SiC MOSFET Comparison 2018 …
Silicon (Si)-based IGBTs have been on the market for more than 30 years. The technology has quickly evolved, reducing the costs and improving performance at the same time. As Si devices approach their physical limits, wide-band-gap devices, in particular made from silicon carbide (SiC), have emerged on the market, offering better performance thanks to their intrinsic properties.
Molten salt synthesis of silicon carbide nanorods using …
Silicon carbide (SiC) nanorods were synthesised by reacting multi-walled carbon nanotubes (CNTs) with Si particles in a NaCl–NaF binary salt for 4 h at 1100–1200 C in Ar. Reaction products were analysed by a coination of X-ray diffraction (XRD) and transmission electron microscopy (TEM), including aberration corrected lattice imaging and electron energy loss spectroscopy (EELS).
