Breakdown field
WebSince wide-band-gap semiconductors have small lattice constants, the bond strength between atoms becomes strong. This means high electric breakdown field and thermal conductivity. The band gap of 4H-SiC is 3.26 eV, and the electric breakdown field is 2.8 × 10 6, which is a very large value compared with that of Si, 3 × 10 5.

Electric current is a flow of electrically charged particles in a material caused by an electric field, usually created by a voltage difference across the material. The mobile charged particles which make up an electric current are called charge carriers. In different substances different particles serve as charge carriers: in … See more In electronics, electrical breakdown or dielectric breakdown is a process that occurs when an electrically insulating material (a dielectric), subjected to a high enough voltage, suddenly becomes a conductor See more Electrical breakdown is often associated with the failure of solid or liquid insulating materials used inside high voltage transformers or capacitors in the electricity distribution grid, usually resulting in a short circuit or a blown fuse. Electrical breakdown can … See more Partial breakdown of the air occurs as a corona discharge on high voltage conductors at points with the highest electrical stress.
