We report the nonlocal desorption of chlorobenzene molecules from the Sið111Þ-ð7 Â 7Þ surface by charge injection from the laterally distant tip of a scanning tunneling microscope and demonstrate remote control of

Nonlocal desorption decays exponentially as a function of radial distance (decay length $100 A) from the injection site. Electron injection at corner-hole and faulted middle adatoms sites couples preferentially to the desorption of distant adsorbate molecules. Molecules on the faulted half of the unit cell desorb with higher probability than those on the unfaulted half.
