WebBand bending implies an electric field and, therefore, a potential difference across the junction. This “built-in” potential Vbi can be found as follows. If we look at the “raw” … 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)
