Modeling electric field of power metal-oxide-semiconductor field-effect transistor with dielectric trench based on Schwarz–Christoffel transformation

Wang Zhi-Gang^†, Liao Tao, Wang Ya-Nan

Schwarz–Christoffel mapping: (a) region II in the original z-plane; (b) the structure after a conformal transformation into the ω-plane; (c) the corresponding structure after the second conformal transformation into the τ-plane.
