Sum-frequency generation on hydrogenated graphene


This project will investigate the ultrafast vibrational energy tranfer from C-H bonds on hydrogenated graphene. Energy tranfer on graphene in general shows some unusual behaviour, but due to the low density of C-H bonds on hydrogenated graphene, the vibrational energy tranfer has not yet been studied, but sum-freuquency generation (SFG) spectroscopy promises to be an ideal tool for this purpose. First vibrationally-resolved SFG spectra from thiols on mica have recently been obtained, see graph on the right.


This project is in collaboration with Drs Cinzia Casiraghi and Andrew Horn, and Drs Rob Lindsay and Andrew Thomas have provided and continue to provide a lot of expertise and money into the project.
