Nanoscale Imaging of Surface Processes at the Heterogenous Interface

Imaging morphological, structural, chemical, and optical properties of material during surface processes is critical for catalytic and optical applications of the materials. In this talk, I will present the development and application of imaging techniques to understand how the molecular environment affects various properties of MoS2 and doped tungsten oxide, phase transition of single micro-sized TiO2 crystals, and synthesis of aluminum nanosheets.

In the second part of my talk, I will present our recent development of plasmonic fiber
nano-probes for nanoscale chemical imaging. The proposed Fiber-based Tip-Enhanced Raman Spectroscopy (F-TERS) combines the spatial (<1 nm) and chemical resolution of TERS with the ease of use of Scanning Near-field Optical
Microscopy. F-TERS can operate in virtually any gaseous and liquid environment, enabling new avenues of nanoscale chemical data collection from any sample analysis in most real-world environments. I will report the design,
fabrication, and characterization of various photonic-plasmonic probes.
