Derivation of built in potential

WebDec 15, 2005 · We demonstrate that the built-in electric fields in nitride dots can provide a strong additional lateral confinement for carriers localized in the dot. This additional … 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)
