Abstract
The invention is a method and device providing very high density information storage on an organomellic DCNQI charge transfer data storage medium. The medium is switched from one state to another through the application of an electric field to the medium by the probe tip of a scanning tunneling microscope resulting in an observable change in the electron density of the surface of the medium.
