“…This result has been reproduced for different metals like Cu, Au, Ag, Pb,... [9]. A slightly more complex method for electrochemical formation of atomic contacts in the case of zinc was reported by Nakabayashi et al [10].…”

Electrochemical methods have recently become an interesting tool for fabricating and characterizing nanostructures at room temperature. Simplicity, low cost and reversibility are some of the advantages of this technique that allows to work at the nanoscale without requiring sophisticated instrumentation. In our experimental setup, we measure the conductance across a nanocontact fabricated either by dissolving a macroscopic gold wire or by depositing gold in between two separated gold electrodes. We have achieved a high level of control on the electrochemical fabrication of atomic-sized contacts in gold. The use of electrochemistry as a reproducible technique to prepare nanocontacts will open several possibilities that are not feasible with other methodologies. It involves, also, the possibility of reproducing experiments that today are made by more expensive, complicated or irreversible methods. As example, we show here a comparison of the results when looking for shell effects in gold nanocontacts with those obtained by other techniques.

“…• As an alternative configuration in which to realize quantized conductance in an electrochemical environment, we point out the earlier work by Nakabayashi et al who fabricated the atomic-scale contact by colliding 2D fractal on a circular ring, as opposed to our vertical configuration. 20 There, the fractal is observed to be grown radially outward from the center of the ring.…”

Copper Tubing-Flexible 1/4-inch cooper tubing used to form the transmitting and receiving coils can be found at most hardware stores. The cost is approximately $1 per foot. The 55-gallon industrial plastic drums that the copper tubing was wrapped around can also be found at many hardware stores and costs approximately $70. Miscellaneous-The WPT experiments also required 18-AWG magnet wire to form the transmitting and receiving loops, capacitors to set the resonant frequency of the loops, coaxial cables, and various rf connector adapters. All of these components can be purchased from Digi-Key Electronics (https://www.digikey.com/).
