Abstract

Volatile and non-volatile solid state molecular switching devices which are electrically addressable and may be used in memory cells, routing circuits, inverters and field programmable devices which may or may not be designed to exhibit diode behavior. The molecular switching devices include certain [2] catenanes as bistable molecules which are sandwiched between two switch terminals. The switches are extremely small and have dimensions which range from several microns down to a few nanometers.
