A prototypical single-molecule chemical-field-effect transistor with nanometer-sized gates was developed to modify hybrid-molecular diode, which was linked to a molecule to a molecule in an Scanning Tunneling Microscope (STM) function. It was found that the effect attributed to an interface dipole, which shifts the substrate work function by ∼ 120 meV. It was also found that the charge transfer complexes responsible for the change in the I-V, were formed between an acceptor covalently bound to the molecule in the tunnelling juction, and a donor coming from the ambient solution. The proof of the principle was also applied for developing monomolecular electronic devices.
