Halide perovskite nanocrystals: Synthesis, transformations and their application in devices

By Prof. Liberato Manna, Istituto Italiano di Tecnologia, Genova

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. Perovskites not only show exceptional primary optoelectronic properties such as a direct bandgap, small exciton binding energy, low carrier recombination rates, ambipolar transport, and tunability of the bandgap covering a wavelength range from the near‑infrared to the ultraviolet, but they are also very attractive for their ease of processability for mass production (e.g. printing from solution) and for the large availability of their chemical components. Following a surge of interest in this class of materials, research on halide perovskite nanocrystals as well has gathered momentum in the last three years. In such a narrow time span, several properties/features of halide perovskite nanocrystals were investigated, among them electroluminescence, lasing, anion-exchange, as well as control of size and shape such that nanocrystals in the quantum confinement regime were recently reported. The present talk will highlight the research activities of our group on halide perovskite and perovskite-related nanocrystals and films, with emphasis on synthesis, as well as structural, chemical, and surface transformations, and their applications in various types of devices.1-3

Bio: Liberato Manna received his PhD in Chemistry in 2001 from the University of Bari (Italy) and worked at the University of California Berkeley as visiting student and then at the Lawrence Berkeley Lab as postdoc until 2003. He was then scientist at the National Nanotechnology Lab in Lecce (Italy) and in 2009 he moved to the Istituto Italiano di Tecnologia, Genova (Italy) as director of the Nanochemistry Department. Since 2010 he is also part-time professor at TU Delft (The Netherlands). His research interests are the synthesis and assembly of inorganic nanostructures for applications in various fields and the study of structural and chemical transformations in nanocrystals.
