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