Bio
Alain Pignolet is Associate Professor and Director of the Ferroic Lab at the University of Québec’s INRS - Centre Enérgie Matériaux Télécommuications in Montreal, Canada. With over hundred publications in peer-reviewed journals such as Applied Physics Letters, Applied Physics A and Advanced Materials, Dr. Pignolet’s laboratory has been on the forefront of research into thin films and nanostructures of smart materials such as ferroelectric, ferroic, and multiferroic oxides. He also contributed to the advancement of Piezoelectric Force microscopy’ or PFM, which enables imaging and characterization of the piezoelectric and ferroelectric properties at the nanoscale, and his research has led to more than 1400 citations in the literature.
Alain Pignolet earned a Bachelor degree in Engineering Physics degree and his Ph.D. in Physics from École Polytechnique Fédérale de Lausanne (EPFL), Switzerland in February 1986 and April 1992 respectively. Joining the IBM Research Division (Thomas Watson Research Center) as a Post-Doc, he began working on high-permittivity relaxor materials, and moved to the Materials Research Laboratory, PennState University, to continue the research, working mainly with Pulsed Laser Deposition (PLD), reactive multi-target magnetron and ion-beam sputtering. Returning to Europe in October 1994, Dr. Pignolet with a Research Staff Position at Max-Planck-Institut für Mikrostrukturphysik (Halle/Saale, Germany) set up a laboratory for deposition of ferroelectric thin films using large area PLD, as well as worked on the optimization and better understanding of piezoresponse force microscopy.
Professor Pignolet has supervised numerous master's student and doctoral students, as well as undergraduate students, postdoctoral fellows and research associates, all involved in the development and characterization (including nano-scale) of advanced functional materials. The ongoing activities and research interests of Professor Pignolet at INRS-EMT include the deposition and growth of epitaxial thin films and nanostructures of functional materials such as ferroelectric, multiferroic, magnetic, or magneto-optic materials for application in micro- and nano-electronics and integrated photonics. His team reported, for the first time, the growth and characterization of epitaxial thin films of Bi¬2FeCrO6 (BFCO), a material that had been predicted to be multiferroic by ab-initio calculation but never synthesized. He and his group showed that compressively strained BFCO thin films and nanostructures exhibit a clear cationic ordering and are multiferroic at room temperature, exceeding the theoretical predictions. He has also investigated the growth of multiferroic composite layers and his group optimized the growth of epitaxial magnetic -Fe2O3 and ferroelectric BiFeO3 composite films. Another current research of Professor Pignolet is investigating the local piezoelectric properties of materials of biological origin, namely biopolymers such as single fibrils of collagen type I and nanocellulose.
