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 ...
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 ...
