Abstract

The NP Junction: Long-Base Depletion Approximation tool is used to approximately calculate, and then graph, the distribution in an n- and p-type junction of :


Charge Density Electric Field Intensity Electrostatic Potential Excess Carrier Concentration Current Density Current Density Amplitude Depletion Width Max Excess Hole Concentration Max Excess Electrons Concentration Junction Capacitance
