Chiroelectricity in 1D Hybrid Semiconductor
Abstract
This Short-Term Innovative Research (STIR) program seeks to explore chiral symmetry breaking in semiconducting ferroelectric materials to achieve strong coupling between electrical polarization and photon. These new chiroelectric materials will provide a mechanism for optically switching ferroelectric domains, a novel pathway to generate force from light. This project will seek to additionally enhance the optical coupling to chiroelectricity using surface-polaritonic resonances (chiral effects should be enhanced by reducing the wavelength of light towards the atomic scale), specifically plasmons at optical frequencies. This project will investigate 1D hybrid organic-inorganic halide crystals as a promising platform to realize these new phenomena. In the hybrid crystal, dipole moment-switchable chiral organic molecules are strongly coupled with the inorganic PbI6 octahedron with strong light absorption. If successful, this project will advance the fundamental understanding of light-matter interaction and open a new field of chirality-enabled electronics.
