Chiral Halide Perovskites for Optoelectronic Applications

Chiral halide perovskites are an exciting platform for integrating chirality with semiconducting properties. This enables a wide variety of chiroptoelectronic properties including visible wavelength circular dichroism, circularly polarized light emission, and the chirality induced spin selectivity effect. This has led to applications in circularly polarized light detectors and spin-light emitting diodes.¹ While these properties and demonstrations are promising, learning to grow chiral halide perovskites effectively and integrate them with device platforms remains a key area of understanding to enable future applications. In this presentation I will discuss the different processing conditions of chiral halide perovskites, the impact on their chiroptical properties, and incorporation with electronic components. Topics included will be spin coating of chiral halide perovskites, the impact of film texture on chiroptical properties, and integration into electronic devices for spintronic and photonic applications. Results in current work integrating chiral halide perovskites with new device platforms will be discussed as seen fit. We believe there is real impact into integrating chiral halide perovskites into device platforms as not only a proof-of-concept for technology demonstrations but also a method to understanding the chiroptoelectronic phenomena of these remarkable materials.
