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) Webwidth in the n-region, the depletion width in the p-region, and the built-in potential at 300K?

WebThis derivation is based on solving the Poisson equation in one dimension – the dimension normal to the metallurgical junction. The electric field is zero outside of the depletion width (seen in above figure) and therefore Gauss's law implies that the charge density in each region balance – as shown by the first equation in this sub-section.
