Tip-Enhanced Ultrasensitive Stokes and Anti-Stokes Raman Spectroscopy in High Vacuum

• We report ultrasensitive Stokes and anti-Stokes Raman spectra of 1,2-benzenedithiol monolayer on Ag film with home-made high-vacuum tip-enhanced Raman spectroscopy (HV-TERS) system. Raman peaks that were orginally very weak were observed experimentally and assigned theoretically. The local temperature was obtained based on the observed Stokes and anti-Stokes HV-TERS spectra.
