Self-Assembled Monolayer of l-Cysteine on Au(111): Hydrogen Exchange between Zwitterionic l-Cysteine and Physisorbed Water

A self-assembled monolayer (SAM) of l-cysteine [HSCH2CH(NH2)COOH] was prepared on a Au(111) surface by vapor deposition in ultrahigh vacuum and was characterized by techniques of temperature-progra...
