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.
Claims18
A solid state molecular switching device comprising:
- a first terminal;
- a second terminal;
- and
- a bistable molecules sandwiched between said first and second terminals wherein said bistable molecule is a [2] catenane.
A method for making a solid state molecular switching device which comprises a step of forming a monolayer of a [2] catenane molecules which are sandwiched between two terminals, said monolayer formation step comprising the step of mixing a sufficient amount of counter ions with [2] cantenane molecules to provide a film forming mixture which is electrically neutral and which is suitable for use in forming said monolayer of [2] catenane molecules.
