Gartner Glossary

Molecular Transistors

The term molecular transistors refers to switching circuits constructed from an individual molecule. Today’s semiconductor devices use “top down” bulk techniques involving lithography; however, the potential exists to grow individual devices using chemical processes in a “bottom up” fashion. This will achieve structures far smaller than is possible using current lithographic techniques. The presence or absence of a single electron can represent on or off states in these small devices.
