Symposium EQ05—Semiconductor Physics of Halide Perovskites—From Fundamentals to Devices

Organic-inorganic halide perovskites (3D, 2D and 0D) have emerged as a novel semiconductor platform for understanding and discovering the rich structure and property relationship arising from the interaction of organic-inorganic interfaces and assemblies. They are formed with organic and inorganic two- dimensional layers, which self-assemble in solution to form highly ordered periodic stacks. Their properties appear to imbibe the best attributes from classical semiconductors, multi quantum wells (MQWs), 2D materials beyond graphene such as transition metal dichalcogenides and organic semiconductors, which has enabled a large compositional and structural phase space and resulted in the discovery of novel and emergent physical properties. In addition to applications for fabricating efficient and stable solar cells and light emitting diodes, and detectors, new properties and behaviors such as water-stability, light- induced structural dynamics, ferroelectricity, Rashba effect, polarized emission from chiral 2DPKs, single photon emitters, and optical modulators. However, despite these advances, there are serious scientific and engineering challenges, which if resolved may pave the path for optoelectronic and energy conversion technologies with state-of-the-art performance and technologically relevant durability.

This symposium is dedicated to bringing together researchers across the globe from a wide range of disciplines including material science, chemistry, condensed matter physics, surface science, device engineering and reliability physics, light matter interactions and photonics to communicate important recent developments, which address key questions pertaining to the fundamental structure-property relationships and applications using novel experimental and theoretical approaches with special focus on: 1. Understanding and tailoring materials chemistry to obtain high purity thin-films 2. Design principles for the selection of spacer cations ± charge, shape, size and heteroatom 3. Advanced structural, and imaging of perovskites 4. Excitonics and photo-phononics 5. Spintronics and spin-orbitronics 6. Electron transport and device physics 7. Device engineering, interfaces, reliability science.

  • Controlled synthesis of halide perovskite from single crystals to thin-films
  • Advanced chemical engineering of halide perovskites with tailored physical properties
  • Photo-phononics and its correlation with structure and chemistry
