ASTM has pubhshed a few selected standards for materials used in the electronics industry, such as gold wire for semiconductor lead bonding, but it does not provide a comprehensive set of standards (see Electrecal connectors). 

Permanent deformation has also been investigated. The rate of flow of gold wires has been found to depend on the electrode potential with a minimum of the rate at E i.c [51Pfu]. The ereep of a lead eleetrode has been studied [69Lik]. (Data obtained with this method are labelled FL).

For all the runs, a calibrated NTD Ge 34B thermistor (3x3x1 mm3) and a Si heater have been used. Electrical connections were made by means of superconducting NbTi wires 25 xm in diameter. The connection between the gold wires of both thermistor and heater and the NbTi leads was done by crimping the wires in a tiny A1 tube (0.1 mg). At the ends of the NbTi wires, a four lead connection was adopted. An AVS47 AC resistance bridge has been used for the thermometry and a four-wire I-V source meter (Keithley 236) for the Si heater was used. 

Here g, go, Tu, e, and h are respectively the conductance, the quantum of conductance equal to 77.48 microsiemens, the transmission through channel i, the electronic charge, and Planck s constant. The idea that conductance can be quantized is a remarkably new one compared with ohmic behavior - Fig. 6 shows experiments that directly demonstrate quantization of transport in atomic gold wires.

Figure 20. A representation of the technique used in the mechanically controllable break junction for recording the current through a single molecule, (a) The gold wire was coated with a SAM of the molecular wires (b) and then broken, under solution (c), via extension of the piezo element under the silicon surface (see Figure 19). Evaporation of the volatile components and slow movement of the piezo downward (see Figure 19) permits one molecule to bridge the gap (d) that is shown, in expanded view, in the insert. The insert shows a benzene-1,4-dithiolate molecule between proximal gold electrodes. The thiolate is normally FI-terminated after deposition end groups denoted as X can be either FI or Au, the Au potentially arising from a previous contact/retraction event.

The experiments were conducted in a one-compartment cell with the reference electrode separated from the main compartment by a Luggln capillary and a closed electrolyte-wetted stopcock. The counter electrode was a gold wire loop and the reference electrode... 

The authors [373] have studied the effect of prolonged cathodic polarization at negative potentials (E < 0.00 V) using both gold wire and rotating disc electrodes. They have shown that Au electrode prepolarized at —0.60 V for 20 min reveals in...
