Our research focuses on the light-matter interaction in a variety of material systems ranging from photo-switching molecules to inorganic 2D crystals. The fundamental understanding of the interaction at the molecular or atomic level guides us to effectively utilize light and control properties of materials. Particularly we investigate in light-induced phase change and molecular arrangement in pursuit of energy storage systems which interact with photons.

Photo-switching molecules absorb light and rapidly respond by structural change

Light induces the phase change of organic materials and controls thermal storage

2D semiconductors show interesting photoluminescence in nanoscale

Microscale phase separation is developed under white light
