Planar nanocontacts with atomically controlled separation

We have developed a technology to reproducibly make gaps with distance control on the single-atom scale. The gold contacts are flat on the nanometer scale and are fabricated on an oxidized aluminum film that serves as a gate. We show that these contacts are clean and can be stabilized via chemical functionalization. Deposition of conjugated...

A method for the manufacture of electrodes

A method of reducing the distance between electrodes, comprising the growth of electrodes by means of electrodeposition in a solution, wherein during the process of growth the conductance over the electrodes is measured and the method is terminated when the conductance has reached a predetermined value. The method according to the invention is...

Nanometer-spaced electrodes with calibrated separation

We have fabricated pairs of platinum electrodes with separation between 20 and 3.5 nm. Our technique combines electron beam lithography and chemical electrodeposition. We show that the measurement of the conductance between the two electrodes through the electrolyte provides an accurate and reproducible way to control their separation. We have...
