Photoelectric Effect: Definition, Equation & Experiment

In solid-state physics, an electron hole (usually referred to simply as a hole) is the absence of an electron from a full valence band. A hole is essentially a way to conceptualize the interactions of the electrons within a nearly full valence band of a crystal lattice, which is missing a small fraction of its electrons. In some ways, the behavior of a hole within a semiconductor crystal lattice is com… WebWhen light shines on a metal, electrons can be ejected from the surface of the metal in a phenomenon known as the photoelectric effect.
