Depletion approximation - PowerPoint PPT Presentation

P-N Junctions

P-N Junctions

P-N Junctions. So far we learned the basics of semiconductor physics, culminating in the Minority Carrier Diffusion Equation We now encounter our simplest electronic device, a diode Understanding the principle requires the ability to draw band-diagrams
