Caption: Scanning tunnelling micrograph of gold atoms on a graphite substrate. The gold atoms, shown as yellow, red and brown, have formed an aggregate of 1x1. 5 nanometres at the base and about 3 atom layers thick. The graphite (carbon) atoms are shown as green. The scanning tunnelling microscope (STM) uses a fine point electrode, a few atoms thick at the tip. This is brought to within a few angstroms of the sample's surface. As the electron clouds of the tip and the sample atoms interact, a small 'tunnelling' current passes. The electrode scans across the surface, moving vertically to maintain the tunnelling current. This motion is then processed to produce a map such as this.
