A WKB approximation in the case that the classical momentum is imaginary can be used to show that the spatial wave function decays exponentially in some regions due to this phenomenon.
Thermionic emission was explained as acting through this phenomenon by Fowler and Nordheim. A WKB approximation in the case that the classical momentum is imaginary can be used to show that the spatial wave function decays exponentially in some regions due to this phenomenon. Oscar Klein described a counterintuitive result in which an increase in potential increases the rate of this phenomenon, and George Gamow discovered the role of this phenomenon in alpha decay. Gerd Binnig and Heinrich Rohrer used this phenomenon to develop a type of microscope which utilizes an electrically conductive metal tip and a voltage bias to measure the current of electrons between the tip and the surface. For 10 points, name this phenomenon that allows particles to "jump" over a barrier, an impossibility in classical physics.
