Single Ag and Ge Atoms on Si(111): Where They Are and How They Move

We study the location and motion of single noble metal and semiconductor atoms on the Si(111) surface using a STM. These STM images contain much visual information. However, we show that physically meaningful conclusions can be deduced only with the help from first principles simulations. This talk will report on our recent theoretical and experimental effort in this direction.
