Input (English): In bulk metals, this effect explains field electron emission and is described by the Fowler-Nordheim type\n equations. Erasing a NOR flash cell is dependent on this effect occurring in the floating gate, and this effect\n can be used to achieve negative differential resistance in a particular type of diode named for Esaki. This\n phenomenon results in the production of a current in the DC Josephson effect. Alpha decay is governed by\n this process, in which a particle's Schrodinger equation is represented as a decaying exponential function.\n For 10 points, name this phenomenon of quantum mechanics in which a particle can go through a\n classically forbidden region.
Output (English): Science
