Provided is a molecular electronic device including an electrode including a conductive polymer electrode layer. The molecular electronic device includes a first electrode; a funtional molecular active layer, self-assembled on the first electrode, including an electroactive functional group having a cyclic compound; and a second electrode disposed on the functional molecular active layer. The second electrode includes a conductive polymer electrode layer contacting with the functional molecular active layer and a metal electrode layer disposed on the conductive polymer electrode layer. The conductive polymer electrode layer of the second electrode prevents damage to the functional molecular active layer, thereby preventing a short circuit in an ultra-thin molecular electronic device.

Molecular electronic device including electrode having conductive polymer electrode layer

Provided are a molecular electronic device and a method of fabricating the molecular electronic device. The molecular electronic device includes a substrate, an organic dielectric thin film formed over the substrate, a molecular active layer formed on the organic dielectric thin film and having a charge trap site, and an electrode formed on the molecular active layer. The organic dielectric thin film may be immobilized on the electrode or a Si layer by a self-assembled method. The organic dielectric thin film may include first and second molecular layers bound together through hydrogen bonds. An organic compound may be self-assembled over the substrate to form the organic dielectric thin film. The organic compound may include an M'-R-T structure, where M&#x2032;, R and T represent a thiol or silane derivative, a saturated or unsaturated Cto Chydrocarbon group which is substituted or unsubstituted with fluorine (F), and an amino(&#x2014;NH) or carboxyl (&#x2014;COOH) group, respectively.
