Catherine Hobbsdensities of electrons and holes in a semiconductor is much smaller than in a metal and those densities can be easily altered by external excitation such as light irradiation. From a thermodynamic viewpoint, even though the internal energies of electrons and holes are fixed at the band-edge energies
