Materials synthesis and characterization:

Study novel photophysical properties and devices:

TERS, a high spatial resolution (< 10 nm) of scanning probe microscope based on the chemical sensitivity of surface-enhanced Raman spectroscopy and plasmonic confinement of electromagnetic field near the metal tip apex. This technique provides insightful light-matter interaction phenomena down to atomic levels.

Study of ultrafast photo-physical phenomena in nanomaterials (spin, charge, charge transfer, and exciton dynamics).
