electron tunneling [i′lek‚trän ′tən·əl·iŋ] (quantum mechanics) The passage of electrons through a potential barrier which they would not be able to cross according to classical mechanics, such as a thin insulating barrier between two superconductors.

| To do so, it exploits the quantum phenomenon of electron tunneling, in which electrons pass through seemingly impenetrable barriers. Cool Chips plc was formed in 1997 to develop and market the Cool Chip(TM)- a wafer-thin disc designed to produce cooling or refrigeration through the use of quantum electron tunneling across a nanometer-scale gap. Some of these theories invoke magnetic spin interactions between electrons and copper ions in the copper oxide layers, while others rely on such effects as electron tunneling between sheets of copper and oxygen atoms in these compounds. |
