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 crystal heterostructures for energy applications. 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.
