Abstract

Desorption of hexanethiol self-assembled monolayers on Au(111) in diethyl ether initiates from domain boundaries and around depressions having weaker lateral interaction than that of densely packed regions. The c(4 × 2) superlattice was observed as domain structure from SAM films formed after desorption, and also some missing-rows were exhibited, indicating the desorption of molecules in these densely packed domains.
