Webof the potential across the region. •Thus far, we have only considered the contact or built-in potential but this is also true for an applied bias. A forward bias is + applied to the p-side, which lowers the built-in voltage barrier (V 0 – V fwd) where V fwd > 0. A reverse bias is – applied to the p-side, which increases the built-in http://optique-ingenieur.org/en/courses/OPI_ang_M05_C02/co/Contenu_05.html http://large.stanford.edu/courses/2007/ap272/kimdh1/ rcw title 25

"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
