"Structure-property Tunability Using Chirality and Symmetry Breaking in Hybrid 2D Perovskites"
Abstract: Hybrid organic-inorganic perovskite (HOIP) semiconductors based on metal halide frameworks offer unprecedented opportunities to tailor structural and electronic properties using the full flexibility afforded by the associated inorganic and organic components, and such tunability offers wide-ranging potential for applications including solar cells, light-emitting devices, detectors, transistors and advanced computing devices. In this talk, I will focus on examining the role that the organic cation can play in introducing or impacting chirality, symmetry breaking and associated phase transitions within HOIPs, as well as on the resulting chiroptical (e.g., circularly dichroism), spin-selective charge transport (e.g., chirality-induced spin selectivity), electronic structure (e.g., conduction band spin splitting), and melting (e.g., allowing for melt-processed film formation and reversible glass-crystal transitions) characteristics of these systems. Recent examples of symmetry-related tunability highlight the promise of using the organic component to control light, charge, and spin within the wide-ranging HOIP family.
