Probing interactions among molecules, substrate, and tip using tip-enhanced Raman spectroscopy.
Tip-Enhanced Raman Spectroscopy (TERS) has shown that spatial resolution <1 nm is possible, but is technically challenging and difficult even in Ultra-High Vacuum at low temperatures with plasmonic substrates. Here we ...
Nanoscale chemical imaging with novel fiber tip-enhanced Raman spectroscopy and microscale study of surface reactions on monolayer MoS2.
Study of molecule-surface interaction dynamics requires nanoscale chemical and topological information. Full dynamic understanding cannot be provided by microscale optical spectroscopy and has been aided by nanoscale imaging ...
