My main project currently focuses on the nanoscale photophysics of the organic semiconductors in which the correlation between 4D-STEM and vibrational EELS will be established to pinpoint the effect of tiny imperfections in the organic molecular crystals on the light emission and absorption. Besides, I also utilize high-resolution STEM imaging and chemical analysis for tribology research while developing new in-situ Raman-Nanoindenation-Heating to elucidate nanoscale mechanics of the tribofim.
