 Poole–Frenkel effect

In solid-state physics, the Poole–Frenkel effect (also known as Frenkel-Poole emission) is a means by which an electrical insulator can conduct electricity.It is named after Yakov Frenkel, who published on it in 1938, extending the theory previously developed by H. H. Poole.Electrons can move slowly through an insulator by the following process.
