Control of light, charge, and spin with hybrid organic-inorganic semiconductors

Hybrid organic-inorganic semiconductors are emerging as important candidates for next-generation optoelectronic and spintronic technologies due to their highly tunable structural and physical properties. However, the mechanisms governing light manipulation and charge dynamics in these materials are not fully understood, limiting their potential applications.

In this talk, I will introduce the control of light polarization, charge flow, and spin transport in hybrid organic-inorganic materials. I will first discuss how the heterogeneous energy landscape in hybrid semiconductors influence charge propagation. Next, I will describe how incorporating chiral organic molecules results in colossal anisotropic spin absorption and explain its relationship to the symmetry breaking in organic and inorganic components. Finally, I will present our recent strategies in developing highly polarized light emitters and integrable full-Stokes polarimetry with the state-of-the-art accuracy.
