Schematic illustrations and STM image of indium atomic wires self-assembled on a Si surface. Indium wires (or indium nanobelts) have a width of approximately 1 nm and are arrayed with a 1.3 nm periodicity. Owing to the template effect of the vicinal wafer, these indium wires were aligned along the step direction. The upper right diagram shows the atomic structure proposed for this system [15].
