Chirality amplification in semiconductors for advanced optoelectronics

Because circularly polarized light (CPL) uniquely carries spin-selective information, chiral optoelectronics offer a powerful platform for developing high-efficiency, spin-based optical devices and driving next-generation photonic technologies. Intrinsically chiral semiconductors can absorb or emit CPL through light-matter interactions, positioning them as highly attractive active materials for advanced optoelectronics. However, their weak chiroptical activities often hinder practical implementation. To address this challenge, researchers have explored a range of strategies aimed at enhancing chiroptical performance. Recent advances in molecular design, processing techniques, and device engineering have led to significant improvements in the chiroptical properties of these materials. This review summarizes recent progress in chirality amplification strategies for semiconductors in advanc…
