Self-Assembled Monolayer Organic Field-Effect Transistors

The use of individual molecules as functional electronic devices was proposed in 1974 and advances in the field of nanotechnology have led to various measurements of electrical properties on the molecular scale for both single molecule devices and devices based on a monolayer of an array of molecules. While single molecule devices are interesting, devices based on an array of molecules are easier to fabricate and could potentially be more reliable. Here, we demonstrate the possibility to modulate the conductance through a single molecular layer (~10 - 20 A) by a third gate electrode.
