This letter reports the selective atomic desorption of Cl atoms adsorbed on an Si(111)7×7 surface by field evaporation using a scanning tunneling microscope (STM). After using STM to study the reaction of the Cl on the surface, the STM tip is placed on the adsorbed Cl and pulse voltage is applied. This results in selective atomic desorption of Cl. Although both desorption and readsorption are observed at a low pulse voltage of +4–+6 V, only desorption occurs at a high pulse voltage over +6 V.
