Abstract

In this talk, I will present ultrastable tip-enhanced Raman spectroscopy (TERS) setup that has a home-built feedback system to compensate possible drift in all three dimensions during hyperspectral Raman imaging. The ultrastable optical nanoimaging system enables long-duration and high resolution TERS imaging of large-sized nanostructured samples far beyond conventional TERS imaging systems. I will show applications of ultrastable TERS imaging of 2D material systems, in which nanoscale characterization of unique physical properties of atomic layer of 2D semiconductors and structural properties of self-assembled biomolecular nanoarchitectures on 2D materials is performed.
