Gold, a precious metal, is arguably the most widely used metal across jewelry and coinage due to its physical properties that are unique to the world of metals. Not only is it a good conductor of heat and electricity, it is unaffected by air and most reagents. It is also used in a wide range of industrial, scientific, and medical applications. More than half a century ago, researchers unveiled the fancy textures on gold surfaces at the nanoscale. Significant efforts have been made toward a better understanding of the surface structures on the atomic scale.
