This model is valid under the assumption that the width of the n-region is sufficiently small so that injected minority carriers diffuse to the metal contact before recombining with majority carriers. ( Depletion Width << Diffusion Length ) The PN Junction: Short-Base Depletion Approximation tool is used to approximatley calculate, and then graph, the distribution in an p- and n-type junction of : - Charge Density - Electric Field Intensity - Electrostatic Potential - Excess Carrier Concentration - Current Density - Current Density Amplitute - Depeletion Width - Max Excess Hole Concentration - Max Excess Electrons Concentration - Junction Capacitance - 1 / C^2 For full details please see Chapter 5 of Streetman's and Banerjee's book " Solid State and Electronic Devices " Sixth Edition.
