After modeling, assigning material, adding loads and applying restraints, we can use the automatic mesh generation function to generate mesh in the stage of preprocessing.
l Assign material to the part.
The material of the part is cast carbon steel, the properties of which are as follows: the value of elastic modulus is 2 x 105MPa，Poisson's ratio is 0.32, yield strength is 270MPa, tensile strength is 500MP, and mass density is 7.8×106㎏/mm.
The basic measures of modifying the original part are as follows: l To ensure a better machine processing performance, we still kept using the same material of original part.

A 500 nm thick layer of N-doped poly silicon has been used as a gate contact material.
For this reason it is proposed, that not only interface states influence the electrical characteristics of the channel, but also defects in the bulk SiC material, that act as charge carrier traps and extend the depletion layer.
