WebAn electric field E forms between the positive ion cores in the n -type material and negative ion cores in the p -type material. This region is called the "depletion region" since the electric field quickly sweeps free carriers out, hence the region is depleted of free carriers. A "built-in" potential V bi is formed at the junction due to E.

"WebWe will relate the built-in potential of the device to the voltage drop across the three layers. Since we have not added any external voltages, the total drop will be due to the built-in potential only. The total potential drop is the sum of the drops over different layers. ϕ14 12 2 3 3 4−= − + − + −ϕϕϕ ϕϕ ϕϕ()( )( ) (1) " - Derivation of built in potential
