Continuity Equation in Semicunductor

It moves from one place to another. In terms of semiconductors, we can say that it satisfies the condition that particles should be conserved. Electrons and holes cannot mysteriously appear or disappear at a given point, but must be transported to or created at given point via some type of carrier action. This equation gives us the relation between the incoming and outgoing charge carriers with the generation and recombination of carriers.
