Directionally Anti-Symmetric Circularly Polarized Emission in Hybrid Semiconductors

Sept. 3, 2025

We demonstrate large and directionally anti-symmetric circularly polarized emission and scattering anisotropies in a low-dimensional chiral organic-inorganic semiconductor, and we comprehensively model the impact of light propagation direction and incident photon polarization on the observed behavior.

Scientific Achievement

We reveal a new mechanism by which light propagation through low-symmetry chiral hybrid semiconductors can produce circularly polarized light emission (CPLE).

Significance and Impact

• Circularly polarized light sources and detectors are key enablers of emerging microelectronic technologies.
• Mechanisms of CPLE in hybrid organic/inorganic semiconductors (HOIS) are poorly understood.
• First demonstration of directionally anti-symmetric CPLE in HOIS—handedness flips with propagation direction.

Research Details

• Detailed polarization-controlled and temperature-dependent photoluminescence in a novel 0D chiral hybrid semiconductor
• Comprehensive wave propagation model to explain complex emission and scattering dependences
