Halide perovskites have emerged as highly versatile materials for optoelectronic and energy-related applications, thanks to their beneficial electronic structure, efficient light absorption, and high tolerance to defects. While thin films have driven rapid technological progress, single-crystal halide perovskites provide a unique opportunity to study intrinsic material properties, understand structure-property relationships and to evaluate the fundamental limits that influence device performance and stability. This symposium is dedicated to recent advances in the growth, characterization, and device integration of single-crystal halide perovskites. Emphasis will be placed on crystal growth strategies, control of structural quality and defects, and on how these factors influence the performance, stability, and reproducibility of optoelectronic, photovoltaic, and emerging devices, including high-energy radiation detectors and memristors for neuromorphic applications. By bringing together crystal growth, advanced characterization, modelling, and device-oriented investigations, the symposium aims to highlight the role of single-crystal halide perovskites of different dimensionalities in advancing optoelectronics, solar energy conversion, and emerging functionalities, while maintaining strong links to the underlying physical mechanisms

Daniela Marongiu is associate professor at the Department of Physics of University of Cagliari (Italy). She obtained a PhD in Nanostructure and Nanotechnology in 2011 from the University of Milano-Bicocca, then she moved to University of Sassari and later in 2013 to Cagliari where she has been an associate professor since 2021. She was visiting researcher at Northwestern University (USA) and Energy Research Institute at NTU (Singapore) in 2019 and 2023. She studied a variety of nanomaterial-related topics and now her main scientific interests involve the growth and characterization of hybrid and all-inorganic halide perovskites in the form of thin films and single crystals for energy applications and neuromorphic devices. Recently she also focused on the synthesis of inorganic double-perovskite micro and nanocrystals with a high photoluminescence quantum yield in the visible range including the doping with rare earths such as Yb and Er for highly efficient NIR emitters and stable phosphors.

Alexander S. Urban studied Physics at the University of Karlsruhe (Germany) obtaining an equivalent to an M.Sc. degree (German: Dipl. Phys.) at the University of Karlsruhe (Germany) in 2006. During his studies he spent a year at Heriot Watt University (UK), where he obtained an M.Phys. in Optoelectronics and Lasers in 2005. He then joined the Photonics and Optoelectronics Chair of Jochen Feldmann at the Ludwig-Maximilians-University (LMU) Munich (Germany) in 2007 where he worked on the optothermal manipulation of plasmonic nanoparticles, earning his Ph.D. summa cum laude in 2010. He expanded his expertise in the fields of plasmonics and nanophotonics in the group of Naomi J. Halas at the Laboratory for Nanophotonics at Rice University (Houston, TX, USA), beginning in 2011. He returned to the LMU in 2014 to become a junior group leader with Jochen Feldmann, where he led the research thrusts on optical spectroscopy, focusing on hybrid nanomaterials such as halide perovskite nanocrystals and carbon dots. In 2017 he was awarded a prestigious Starting Grant from the European Research Council and shortly after that in 2018 he received a call as a Full Professor of Physics (W2) at the LMU. Here, he now leads his own research group working on nanospectroscopy in novel hybrid nanomaterials.
