Issue no Total pages First page Last page File name Date req Artnum Cover date Abstract Conductance of nanoscale junctions consisting of a molecular monolayer in contact with different metal electrodes is studied. The characteristic energy scales of conductance are determined from the temperature dependence and from the non-linear current–voltage characteristics. Conductance measured at small b...
متن کاملFabrication of metallic electrodes with nanometer separation by electromigration
A simple yet highly reproducible method to fabricate metallic electrodes with nanometer separation is presented. The fabrication is achieved by passing a large electrical current through a gold nanowire defined by electron-beam lithography and shadow evaporation. The current flow causes the electromigration of gold atoms and the eventual breakage of the nanowire. The breaking process yields two...
متن کاملControlled fabrication of metallic electrodes with atomic separation
We report a technique for fabricating metallic electrodes on insulating substrates with separations on the 1 nm scale. The fabrication technique, which combines lithographic and electrochemical methods, provides atomic resolution without requiring sophisticated instrumentation. The process is simple, controllable, reversible, and robust, allowing rapid fabrication of electrode pairs with high y...

متن کاملComparison of SAM-Based Junctions with Ga2O3/EGaIn Top Electrodes to Other Large-Area Tunneling Junctions
This paper compares the J(V) characteristics obtained for self-assembled monolayer (SAM)-based tunneling junctions with top electrodes of the liquid eutectic of gallium and indium (EGaIn) fabricated using two different procedures: (i) stabilizing the EGaIn electrode in PDMS microchannels and (ii) suspending the EGaIn electrode from the tip of a syringe. These two geometries of the EGaIn electro...
