Strong Light-Matter Coupling and Polariton Physics
Strong Light-Matter Coupling and Polariton Physics
Molecules placed close to an optical mode in terms of space and energy can form new hybrid states, which consist of half-matter and half-light quasi-particles. This opens a new route to control the functions of molecules without changing their chemical structures.

Organic Electronics and Device Physics
Device physics is essential to build desired device structures and study various fundamental physics therein. Organic field-effect transistors can provide a direct determination of charge carrier mobility and transport mechanisms in organic solids at different charge concentrations controlled by electrical gating.
