Single-crystal films of gold and silver in (001) orientation were deposited upon sodium chloride cleavage surfaces. The resultant film structures were determined by transmission electron diffraction techniques. Irrational reflections resulting from double diffraction at twin boundaries and stacking faults were observed. The minimum substrate temperature necessary for complete epitaxy was found to be dependent upon the deposition rate. The condensation coefficients for specific film-substrate combinations were determined to be a ...
The properties of anodic oxide films on Au in lN HClO4 were studies as a function of time (2 sec to 5 min) and of potential of formation (1450 to 1850 mv vs. Pt, H2/H+ in the same solution). Over the range observed (10-20% of the total oxide), the oxide grows slowly with time, apparently according to Elovich kinetics, although the constants are potential-dependent. Oxides formed at longer times at ...
Gold single crystals of five different orientations were tested in tension at room temperature. The results were qualitatively similar to the observations in aluminum and silver, except for the < 100 > orientation. (Author)
