Silicon Carbide

The material SiC: Acheson production, abrasive grit and the single crystals used in power electronics.

  From abrasive grit to semiconductor: silicon carbide in power electronics

  Why 4H-SiC suits power semiconductors: breakdown field, thermal conductivity, doping and native oxide, the weak spot at the MOS interface, and why sawing SiC crystals is a challenge of its own.

  Silicon carbide: the material, the Acheson process and its uses

  What silicon carbide is, how it forms from quartz sand and coke in the Acheson furnace, why there is green and black SiC, how grit is made from it, where it is used and what occupational health rules apply.
