This research direction focuses on low-dimensional materials, micro/nano structures, and optoelectronic devices, studying novel optical phenomena, photophysical mechanisms, and developing new optoelectronic devices across the visible to mid-infrared spectrum under micro/nano-scale and extreme conditions.

Our research can be summarized into three main areas: innovative optical measurement techniques for characterizing micro/nano structures, in-depth exploration of the photophysical mechanisms of low-dimensional materials, and investigation of light manipulation applications based on micro/nano devices. By developing novel scanning optical microscopy with ultra-high spatiotemporal resolution and optical microscopy systems under extremely low temperatures and strong magnetic fields, we can measure various optoelectronic signals such as fluorescence, Raman, absorption, reflection, photocurrent, nonlinear optical, pump-probe, and near-field optical signals across different physical environments and spatiotemporal scales.

This research direction, through in-depth studies of photophysical phenomena at the micro/nano scale, under extreme environments and multidimensional control—such as photogenerated electricity, electrically controlled light, light-matter interactions, plasmonic manipulation, quasiparticle interactions, and ultrafast dynamics—can provide the theoretical foundation and technical support for the development of optoelectronic detection, optoelectronic devices, all-optical switches, light field control, and optical microscopy characterization systems.
