Gallium nitride (GaN) and silicon carbide (SiC) are relatively similar in both their bandgap and breakdown field. Gallium nitride has a bandgap of 3.2 eV, while silicon carbide has a bandgap of 3.4 eV. While these values appear similar, they are markedly higher than silicon''s bandgap. GaN vs SiC: Silicon Carbide and Gallium Nitride Compared
Today, the most widely used material for power semiconductors is silicon. Silicon is inexpensive to produce and the technology is well understood. However, there are other materials, the so called compound power semiconductors, such as Silicon Carbide and gallium-nitride that are much more efficient conductors of electricity.

The advantages and disadvantages of Silicon carbide and gallium nitride . Silicon carbide, also known as silicon carbide, is made by using quartz sand, petroleum coke, wood chips and other raw materials through high-temperature smelting in an electric resistance furnace. Silicon carbide is also a rare mineral in the nature - Moissanite.
Jan 01, 2016· Silicon nitride, on the other hand, is strong enough to be used without a baseplate, which reduces the overall cost of the material when used for packaging. The result of these tests, with further work ongoing, has increased the confidence in SiC as a key material for high-efficiency power electronics in systems that need high reliability.
