Chiral metal halide perovskites and perovskite-inspired materials have garnered significant attention in recent years due to their peculiar properties such as circular dichroism, polarized photoluminescence, non-linear chiroptical effects, and spin-polarized carriers. All these characteristics make them promising materials for chiroptoelectronics, spintronics and ferroelectrics. In addition, the vast tunability of hybrid metal halides due to their organic-inorganic duality in terms of chemical composition and structural motifs allows to synthesis, design and tailor materials with specific and/or optimized properties. However, the design and engineering of novel compositions requires a deep understanding of the structure-property correlation in chiral hybrid metal halides which is still not fully addressed both from an experimental and computational point of view. This deep understanding is also an important requisite for device manufacture. The symposium aims to provide a platform for researchers and experts in the filed of chiral metal halides to share recent finding covering all the aspects from the materials design and synthesis, computational and experimental characterization, and device engineering.

Dr. Beatriz Martín-García received her Ph.D. in Chemical Physics (Cum Laude) from University of Salamanca (Spain) in 2013. Then, she joined Istituto Italiano di Tecnologia (Italy) under the Graphene Flagship project working during almost 6 years on the modulation of optoelectronic properties of different materials (nanocrystals, 2D materials and hybrid metal-halide perovskites) by chemical-design and surface-functionalization strategies for their integration in solar cells, photodetectors and memories. She is currently an Ikerbasque researcher and Ramón y Cajal fellow at CIC nanoGUNE BRTA, leading a research line developing tailor-made low-dimensional materials and studying them by Raman and photoluminescence spectroscopy techniques to drive the selection of desired properties for their integration in optoelectronic and spintronic devices.
