For ten points, name this  phenomenon in which the probability distribution of a particle's presence is partially beyond a classically forbidden barrier, present in a certain type of scanning microscope.
This phenomenon is at the center of a phenomenon in which particles below the Fermi level exhibit cold emission. It also explains how SQUIDs work because of the Josephson effect, in which there is electron flow between superconductors connected, and it also explains how enzymes work.
