DESCRIPTION:Prof. Liberato Manna\, Istituto Italiano di Tecnologia\, Genov
 a\nHalide perovskite semiconductors can merge the highly efficient operati
 onal principles of conventional inorganic semiconductors with the low‑te
 mperature solution processability of emerging organic and hybrid materials
 \, offering a promising route towards cheaply generating electricity as we
 ll as light. Perovskites not only show exceptional primary optoelectronic 
 properties such as a direct bandgap\, small exciton binding energy\, low c
 arrier recombination rates\, ambipolar transport\, and tunability of the b
 andgap covering a wavelength range from the near‑infrared to the ultravi
 olet\, but they are also very attractive for their ease of processability 
 for mass production (e.g. printing from solution) and for the large availa
 bility of their chemical components. Following a surge of interest in this
  class of materials\, research on halide perovskite nanocrystals as well h
 as gathered momentum in the last three years. In such a narrow time span\,
  several properties/features of halide perovskite nanocrystals were invest
 igated\, among them electroluminescence\, lasing\, anion-exchange\, as wel
 l as control of size and shape such that nanocrystals in the quantum confi
 nement regime were recently reported. The present talk will highlight the 
 research activities of our group on halide perovskite and perovskite-relat
 ed nanocrystals and films\, with emphasis on synthesis\, as well as struct
 ural\, chemical\, and surface transformations\, and their applications in 
 various types of devices.1-3\n \nKeywords: halide perovskites\; nanocryst

 the University of Bari (Italy) and worked at the University of California 
 Berkeley as visiting student and then at the Lawrence Berkeley Lab as post
 doc until 2003. He was then scientist at the National Nanotechnology Lab i
 n Lecce (Italy) and in 2009 he moved to the Istituto Italiano di Tecnologi
 a\, Genova (Italy) as director of the Nanochemistry Department. Since 2010
  he is also part-time professor at TU Delft (The Netherlands). His researc
 h interests are the synthesis and assembly of inorganic nanostructures for
  applications in various fields and the study of structural and chemical t
 ransformations in nanocrystals.\n\n \n
