Phys. Rev. Lett. 92, 188303 (2004) [4 pages]Prototypical Single-Molecule Chemical-Field-Effect Transistor with Nanometer-Sized Gates
F. Jäckel1, M. D. Watson2 *, K. Müllen2, and J. P. Rabe1 † Received 22 September 2003; published 6 May 2004 A prototypical single-molecule chemical-field-effect transistor is presented, in which the current through a hybrid-molecular diode is modified by nanometer-sized charge transfer complexes covalently linked to a molecule in an STM junction. The effect is attributed to an interface dipole which shifts the substrate work function by ∼120 meV. It is induced by the complexes from electron acceptors covalently bound to the molecule in the gap and electron donors coming from the ambient fluid. This proof of principle is regarded as a major step towards monomolecular electronic devices. ©2004 The American Physical Society
