    Photo-induced phenomena in molecules/materials play a significant role in energy device applications. However, using bulk systems has reached the limit in their functions, performance, and regarding application range. Low-dimensional quantum systems have recently emerged as appealing resources for the next generation energy devices based on their significantly improved photoenergetic performances. Hence, understanding quantum light-
    matter interactions at their natural length scale is of fundamental significance in physics, chemistry, and engineering. Our research focuses on discovering and controlling a range of new functions and behaviors of low-dimensional quantum materials through the advanced tip-enhanced near-field spectroscopy and imaging techniques exceeding the current instrumental limits. Our specific research topics are as follows:

    • Developing advanced near-field microscopies beyond the current instrumental limits to extend nano-imaging into a wider range of optical spectroscopic modalities, including linear elastic (Rayleigh) and inelastic (Raman, photoluminescence; PL, VIS absorption, IR), nonlinear (second-harmonic generation; SHG), and ultrafast (~ps) spectroscopy, from UV to mid-IR/THz, in various interacting environments, e.g., ultra-high vacuum (UHV), cryogenic, and liquid.
    • Discovering new emerging physical properties, e.g., coupling and energy transfer, in single- and bio-molecular, quantum, optoelectronic, and multiferroic systems, as well as probing structure, field distribution, heterogeneity, and dynamics on the nanoscale.
    • Breaking new ground in active control of nanoscale light-matter interactions through the controllable nano-opto-mechanical plasmonic tip.
