| Research Abstract |
Scanning tunneling microscope (STM) combined with near field Raman spectroscopy is constructed in this research for hybrid imaging and chemical analysis. SWNT is selected as our sample for tip enhanced Raman spectroscopy (TERS) because it has very strong Raman signal and clear morphology. We obtained spectrally resolved TERS images at different Raman modes with 1.7 nm spatial resolution. For the first time, the local defect origin of D band, diameter factor of resonance condition, and tube bundling effect are all visualized in real space. We are so exciting to have such high resolution tool and it may change the views and ways of analytical chemistry as well as optics and spectroscopy. This opens new possibilities to investigate nanoscale physics, chemistry, and biology.
