Summary

The behavior of molecules at surfaces directly influences important technologies such as the fabrication of microchips. In his commentary, King discusses results reported by McEllistrem et al. and by Brown et al. in this issue of Science in which scanning tunneling microscopy was used to image surfaces. McEllistrem et al. have been able to take snapshots of dangling bonds on a silicon surface, while Brown et al. have directly imaged a precursor state on silicon. According to King, these studies represent a new level of maturity in the ability of scanning probe microscopies to aid surface scientists.
