Self-assembled organic and fullerene monolayers characterisation by two-color SFG spectroscopy: a pathway to meet doubly resonant SFG process

Research output: Contribution to journalArticle

Abstract

Two-colour sum-frequency generation (two-colour SFG) spectroscopy was used to probe both vibrational and electronic properties of 1-dodecanethiol/Ag(111), Au(111), and Pt(111), of 5-[p-(6-mercaptohexoxy)-phenyl]-10,15,20-triphenylporphin/Pt(111), and of C60/Ag(111). The role of the various physical parameters determining the sum-frequency generation (SFG) intensity equation is highlighted. The enhancement of the non-linear second order susceptibility in the aforementioned interfaces is explained in terms of metal interband transition, molecular electronic transition and of electron'phonon coupling, respectively.
