Nano switch could store memory using coordinated 'dance' of atoms

more »

(Phys.org) —In one of the tiniest switches ever made, five atoms appear to "dance" around each other in a complex choreographic sequence, with their final arrangement corresponding to one of two stable states. This concerted motion of multiple atoms is unlike that in other nano switches, which typically involve movement of only a single atom or molecule. The motion of multiple atoms gives the switch a major advantage: due to its stability, it is one of the few atomic-scale switches capable of operating at room temperature instead of cryogenic temperatures.
