Higher band-gap: The SiC band-gap is almost 3 times that of silicon A semiconductor that, overall, has better characteristics would be a far better choice for many appliions ranging from high power radio equipment to processor design whereby small high-speed transistors could easily stay cool, operate efficiently, and continue to improve processing capabilities.
Abstract: The advantages offered by wide band gap materials enable the design of converters with high power density for high performance appliions. This paper presents the design and test results for a high frequency (400kHz) hard switched two level silicon carbide based three phase inverter.
The valence–conduction band gap is three times bigger, which helps to reduce switching losses by 90%. Silicon-Carbide-based high-performance components exhibit efficiency levels close to 100%. At the same time, they can transfer much higher current densities.
A band gap, also called a bandgap or energy gap, is an energy range in a solid where no electron states can exist. The term is used in solid-state physics and chemistry.Band gaps can be found in insulators and semiconductors.In graphs of the electronic band structure of solids, the band gap is the energy difference (in electron volts) between the top of the valence band and the bottom of the

Semiconductor materials Solid-state materials are commonly grouped into three classes: insulators, semiconductors, and conductors. (At low temperatures some conductors, semiconductors, and insulators may become superconductors.)The figure shows the conductivities σ (and the corresponding resistivities ρ = 1/σ) that are associated with some important materials in each of the three classes.
