Atomic Scale Desorption and Fragmentation with the STM
The STM is not only a powerful probe of the atomic structure of surfaces, but is also a unique tool for the atomic scale modification and manipulation of materials. I will illustrate this new application of the STM with three examples: First, I will discuss a general approach for the selective breaking of strong chemical bonds, which we use to manipulate Si atoms on Si(111) at room temperature. I will then use the manipulation of a Au(111) surface to show that “local” modifications can couple with long-range elastic surface interactions to lead to large scale atomic rearrangements. Finally, I will discuss the use of electrons from the STM tip to induce the dissociation of individual molecular adsorbates.
