Topic: Organic-Inorganic Perovskites: Unprecedented Opportunities for Emerging Semiconductor Design and Application

Although known for many years, organic-inorganic perovskites and related hybrid semiconductors are receiving extraordinary recent attention because of the associated unique characteristics of these systems, which include a broad range of facile and low-temperature film and crystal processing approaches. Unlike traditional inorganic semiconductors (e.g., silicon or GaAs), hybrid systems offer the opportunity to combine inorganic (e.g., desirable semiconducting, spin-related, and/or stability characteristics) and organic (e.g., chemical tunability/versatility, chirality, luminescence, and mechanical flexibility) functionality within a single molecular-scale composite. This talk will provide a historical perspective for this materials class, integrated with a discussion of several contemporary examples of combining functionality to unlock unprecedented property tunability—e.g., versatile self-assembling organic-inorganic quantum-well structures, hydrogen-bonding mediated chiral transfer for control over spin-related properties, and materials design for melt processing and glass-crystalline transitions (e.g., phase-change materials). Outstanding functionality and versatile processing form two pillars for structure-property control and prospective future photovoltaic, light-emission, photodetection, next-generation computing, and spintronic applications within this rapidly evolving materials family.
