A phenomenon that can occur in both insulating and semiconducting materials (solids, liquids, or gases), allowing very large currents to flow within materials which are otherwise good insulators. Occurs when the electric field in the material is great enough to accelerate free electrons to the point that, when they strike atoms in the material, they can knock other electrons free: the number of free electrons is thus increased rapidly as newly generated particles become part of the process.
Conduction (electrical)
The movement of electrically charged particles through a transmission medium (electrical conductor). The movement of charge constitutes an electric current. The charge transport may result as a response to an electric field, or as a result of a concentration gradient in carrier density, that is, by diffusion .
Through heating resulting from the flow of current.
Dielectric Heating
(also known as electronic heating, RF heating, high-frequency heating) The phenomenon in which radiowave or microwave electromagnetic radiation heats a dielectric material, especially as caused by dipole rotation.
