Halide perovskite semiconductors can merge the highly efficient operational principles of conventional inorganic semiconductors with the low‑temperature solution processability of emerging organic and hybrid materials, offering a promising route towards cheaply generating electricity as well as light. Following a surge of interest in this class of materials, research on colloidal halide perovskite nanocrystals (NCs) has gathered momentum in the last decade. My talk will highlight several findings of our group on their synthesis, for example our studies on the influence of various exogenous cations on the growth of perovskite NCs, and our attempts to control their growth kinetics. I will also cover our recent work on the growth of perovskite NCs with peculiar shapes (for example hollow structures) and NC heterostructures, where a perovskite domain is interfaced with a domain of another material, and I will discuss their use as photocatalysts. I will also provide an overview post-synthesis strategies to improve the stability of the NCs and their subsequent use in light emitting devices (displays and light emitting diodes). The last part of the talk will highlight our research on the ordering of NCs in superstructures.
Liberato Manna received his Ph.D. in Chemistry in 2001 from the University of Bari (Italy) and worked at U.C. Berkeley (USA) as a visiting student and then at the Lawrence Berkeley National Laboratory (USA) as a Postdoc until 2003. He was then scientist at the National Nanotechnology Lab in Lecce (Italy), and then moved to the Istituto Italiano di Tecnologia (IIT), Genova (Italy), in 2009 as head of the Nanochemistry Department. From 2010 to 2021 he was also part-time Professor at TU Delft (The Netherlands). Currently, he is also Associate Director of IIT for Blue Sky Research, Associate Editor of Nano Letters (American Chemical Society) and part-time professor at the University of Genova. His research interests include the synthesis and assembly of colloidal nanocrystals, the study of structural, chemical, and surface transformations in nanoscale materials, and their applications in energy, photonics, and electronics.
