Abstract

An invisible monolayer? Oxidation of an octylsilane monolayer (see graphic) chemisorbed onto Au(111) yields two surprising results. The 23×equation image Au surface reconstruction typical of a clean gold surface forms underneath the siloxane monolayer. In addition, the physisorbed alkylsiloxane monolayer is transparent to scanning tunneling microscopy imaging.
