Abstract

The surface roughness of a Au(110) electrode was studied as a function of electrode potential. The electrode potential was cycled between the double layer region and the oxide and hydrogen regions. Measurements of the crystal truncation rod passing through the (111) reflection were made ex-situ. The results reveal that the surface roughness is not significantly changed by cycling the potential between the double layer and the oxide regions, (.3V – 1.4V vs. Pd/H2, 0.1M HClO4). The roughness is decreased when the potential is cycled into the hydrogen region, -0.4V.
