Symposium QT01-Chirality and Spin in Halide Perovskites

Halide perovskites have emerged as a new class of semiconductors with exceptional material properties, making them promising candidates for a plethora of spin- and optoelectronic applications. Despite their rapid development, halide perovskites remain highly enigmatic, simultaneously featuring properties reminiscent of organic and traditional inorganic semiconductors. The origin and extent of novel features, such as defect tolerance or high ion mobility, are not fully understood. Even much less is known about these materials with respect to the influence of structural chirality on their properties. Spin properties in halide perovskites are in early infancy, despite their great potential due to an inverted spin-orbit coupling structure originating from lead atoms as well as chirality. To date, a lack of comprehensive insight into the interplay between structure and morphology, composition, dimensionality, and impact of electronic and phononic response in these materials, impedes the further advancement of halide perovskites for spin-optoelectronic applications.

This symposium will be a platform for researchers whose work addresses underlying fundamental material aspects related to chirality and spin in halide perovskites. Research topics covered in the symposium will include, among others, the latest advances in photophysics, charge and spin transport, ultrafast spectroscopy, band-structures and spin textures, phonon-carrier interactions, magneto-optical properties, circularly polarized light emission, and mapping/imaging techniques. As the prevalence of individual features can depend on the perovskite morphology, submitted abstracts may focus on bulk-like 3D thin films and single crystals or explore low-dimensional structures, such as 2D Ruddlesden-Popper phases or nanocrystals. Sessions focusing on the theoretical description of these phenomena and the development of new computational methods and approaches, for example, machine learning, will complement the experimental parts of this symposium.

Topics will include:

  • Chiral perovskites: synthesis & properties
  • Experimental & computational characterization of charge & spin transport
  • Ultrafast processes in halide perovskites (hot carriers, localization, spin depolarization etc.)
  • Micro- and nano-scale imaging of perovskites
  • Coupling of charge carriers, excitons, phonons, polarons to spin
  • Low-dimensional perovskites (nanocrystals, layered perovskites, 2D heterostructures)
  • Magnetic dopants and their spin-properties
  • Band structure calculations & theoretical modelling of optoelectronic properties; materials discovery
  • Emerging properties & applications (ferroelectricity, polaritonics, chiral light emission, quantum applications, etc.)
