Understand how photons interact with direct and indirect band gap semiconductors
Understand generation–recombination of excess carriers, possibly through trap sites
Introduce quasi-Fermi levels in nonequilibrium
Calculate diffusion currents from carrier concentration gradients and diffusivity
Use the continuity equation to study time dependence of carrier concentrations
Most semiconductor devices operate by the creation of charge carriers in excess of the thermal equilibrium values. These excess carriers can be created by optical1 excitation or electron bombardment, or as we shall see in Chapter 5, they can be injected across a forward-biased p-n junction. However the excess ...
