  • Highly polarizable 3D organic perovskites and electro-optic materials comprising same
    Patent number: 11970501
    Abstract: The present invention relates to highly polarizable 3D organic perovskites of the general formula ABX3, prepared by introducing halogen functional groups in the A-site cation (in which the A and B sites are occupied by organic cations and the X site is a monovalent non-metallic counterion). The (DCl)(NH4)(BF4)3 crystal exhibits a strong linear electrooptic (EO) effect with an effective EO coefficient of 20 pmV?1, which is 10 times higher than that of metal halide perovskites. These 3D organic perovskites are solution processed and compatible with silicon, and illustrate the potential of rationally-designed all-organic perovskites for use in on-chip modulators, electro-optic devices, piezoelectric devices, or silicon photonics devices.
