The solution, says Will Draper, is to use silicon carbide chips to reduce the size of the power electronics and increase operating temperature. Hybrid electric vehicles (HEVs) represent a major challenge for automobile designers, especially in terms of their size, weight, the choice of electronic systems and controls, as well as the thermal management of these additional systems.

Elemental silicon has the same structure, as does silicon carbide (SiC), which has alternating C and Si atoms. The structure of crystalline quartz (SiO 2 ), shown in Section 12.1, can be viewed as being derived from the structure of silicon by inserting an oxygen atom between each pair of silicon atoms.

carbide - definition and meaning
carbide: A binary compound consisting of carbon and a more electropositive element, especially calcium. Boron carbide is one of the two most commonly used materials in the manufacture of the ceramic ballistic-protective plates used today by America’s frontline troops.
Tungsten Carbide Cobalt Powder | Nanochemazone
Tungsten carbide is a chemical compound (specifically, a carbide) containing equal parts of tungsten and carbon atoms. In its most basic form, tungsten carbide is a fine gray powder, but it can be pressed and formed into shapes through a process called sintering for use in industrial machinery, cutting tools, abrasives, armor-piercing shells and jewelry.

CSA apult - What are Compound Semiconductors?
With a single element, it is possible to scale-up the manufacturing process to make highly complex silicon chips in large volumes, and hence 80% of the world’s semiconductors use silicon. The remaining 20% use compound semiconductors, which coine two or more elements from the periodic table to form a compound.
