Topics include: Device structure for pn junction, Energy band diagram at equilibrium for pn junction ... Recombination and generation in the depletion region, Non-ideal current, Effect of band ...

The diagram illustrates the basic structure of a p-n junction diode with p-type silicon on one side, n-type silicon on the other, and the anode and cathode terminals. It also includes the symbol for a ...

which allows only the unidirectional flow of electrical current through the p-n junction. In semiconductors, the p-n junction is formed through the diffusion of dopants, ion implantation, or epitaxy.
