提出了一种典型的单分子化学场效应晶体管，其中通过混合分子二极管的电流通过共价连接到STM结中的分子的纳米尺寸的电荷转移复合物进行修改。这种效应归因于界面偶极子使衬底功函数移动了约120 meV。它是由与差距中分子共价结合的电子受体和来自环境流体的电子供体形成的复合物诱导的。这一原理的证明被认为是迈向单分子电子器件的重要一步。
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 similar to120 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.
