About this document
Derivation of Depletion Width (W) by testpro1103 is a document available to read on EtoBox.
The document details the derivation of the depletion width for a p-n junction, based on the depletion approximation which assumes the region is free of charge carriers. It outlines key assumptions, a step-by-step derivation involving charge density, electric field, built-in potential, and ultimately provides the formula for calculating the total depletion width. The final expression for the depletion width (W) is derived in terms of the built-in potential (Vbi), permittivity (ϵ), and doping concentrations (
