Fabricating and Controlling Molecular Self-Organization at Solid Surfaces:  Studies by Scanning Tunneling Microscopy

This account presents a summary of recent work describing the control and fabrication of self-organized molecular adlayers on solid substrates. These results demonstrate that molecules, under appropriate conditions, will self-organize into well-ordered monolayers on various solid surfaces. Using scanning tunneling microscopy (STM) to probe the structure of these molecular architectures, it is possible to determine the surface quality to single molecule resolution. The surface structures can be controlled by external stimuli such as electrode potential and UV-light. The ability to control how these adlayers form is important for constructing surface molecular architectures with useful properties.
