Dr. Michele Perego is interested in the development of new bottom-up approaches for the synthesis of functional nanostructured materials with typical feature dimension below 20 nm. The focus of his research activity is on one side the investigation of fundamental issues related to the self -assembly processes in polymeric films and on the other side the use of these macromolecules to synthesize functional nanostructures. This result is obtained either by using the nanostructured polymeric material as a mask for subsequent processing of semiconducting or dielectric materials or by introducing proper functionalities in the macromolecules to use the self assembled polymeric nanostructures as active materials in electronic, optoelectronic or photovoltaic devices. He is currently working on block copolymer self assembly to fabricate inorganic nanostructures. He is interested in the understanding the fundamental issues related ot the doping of semiconductor nanostructures and in the development of new self-assembly strategies to control doping of semiconductors at the nanoscale.

Short Bio: Michele Perego received the Degree in Physics from Università degli Studi dell'Insubria in 1999. In February 2004 he obtained the PhD in Physics, Astrophysics and Applied Physics from the University of Milano for his work on the ToF-SIMS characterization of nanocrystals embedded in thin oxide films. During his PhD he worked in the EC project NEON on semiconducting nanocrystals for memory application. In the period 2004-2007 he has been Post-Doctoral Fellow at the MDM Laboratory. He has been employed as a Research Scientist from 2007 to 2019 at IMM-Unit of Agrate Brianza, where he is currenlty working as Senior Research Scientist.
Skills: He is expert in the synthesis and characterization of nanostructured materials for advanced microelectronic, optoelectronic and photovoltaic applications. He is expert in Secondary Ion Mass Spectrometry and X-ray photoelectron Spectroscopy. He is interested in other analytical techniques for the characterization of thin films. He is trained on ultra high vacuum systems and he is experienced in clean room processes for microelectronic and optoelectronic applications.
Projects: He coordinated the national project MATRIX (2007-2009) on the fabrication of 2 dimensional arrays of Si nanoparticles by means of block copolymer technology. This two years project was funded by Fondazione Cariplo. He was the coordinator of the international project NANOBLOCK (2009-2012). This project was funded by the Nanosci-ERA consortium and aimed at the integration of top-down and bottom-up approaches for the manipulation of semiconducting and metallic nanostructures. He was the principal investigator for MDM in the European project NanoPV (2011-2014) devoted to the implementation of nanostructured materials for high efficiency solar cells. He is currently involved in the research project IONS4SET (2016-2020) for the fabrication of single electron transistors.
Pubblications: He holds more that 120 pubblications in peer reviews journals, 6 cover pages and 3 extended patents. He is regularly tutoring master and PhD students, and supervising post-docs. He presented various invited seminars at Universities and Schools and at International conferences.
