With over hundred publications in peer-reviewed journals, 3 book chapters and over 1500 citations, Dr. Pignolet has been on the forefront of research into synthesis and characterization of thin films and nanostructures of advanced functional materialssuch as ferroelectric, ferroic, and multiferroic oxides. He also contributed to the advancement of piezoelectric force microscopy which enables imaging and characterization of the piezoelectric and ferroelectric properties at the nanoscale.Alain Pignolet earned a Bachelor degree in Engineering Physics and his Ph.D. in Physics from \u00c9cole Polytechnique F\u00e9d\u00e9rale de Lausanne (EPFL), Switzerland. 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, The Pennsylvania State University, to continue his research, working mainly with Pulsed Laser Deposition (PLD), reactive multi-target magnetron and ion-beam sputtering. From October 1994 to December 2001, Dr. Pignolet has hold a Research Staff Position at Max-Planck-Institut f\u00fcr Mikrostrukturphysik (Halle\/Saale, Germany) setting up a laboratory for deposition of ferroelectric thin films using large area PLD, as well as working on the optimization and better understanding of piezoresponse force microscopy.Professor Pignolet\u2019s present research interests and ongoing activities include the growth and studies of epitaxial thin films and nanostructures of functional materials such as ferroelectric, multiferroic, magnetic, magneto-optic or magnetoelectric materials for application in micro- and nano-electronics and integrated photonics. He has a particular interest for novel room temperature multiferroic and magnetoelectric materials.In particular, he has investigated the growth of multiferroic nanocomposite heterostructures, such as epitaxial magnetic g-Fe2O3 and ferroelectric BiFeO3 composite films, as well as epitaxial composites films of magnetic BaFe12019 and ferroelectric Ba2LnFeNb4O15 (Ln = Eu, Nd, Sm). Professor Pignolet\u2019s team was also the first to report the growth and characterization of epitaxial thin films of Bi\u00ad2FeCrO6 (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 epitaxial thin films and nanostructures exhibit multiferroic properties at room temperature, exceeding the theoretical predictions.Similarly, epitaxial strains have also been used to stabilize the metastable epsilon phase of ferrite (\u03b5-Fe2O3), a hard magnetic material potentially multiferroic at room temperature, in addition to possess the largest coercive field among oxides and to exhibit a magnetic resonance frequency in the low THz range.\u00a0 \u03b5-Fe2O3 epitaxial films therefore exhibit, in a single material, a number of properties of interest for various applications.\u00a0\u00a0Scientific Activities\u00a0Member of the FRQNT multidisciplinary \u00e9valuation committee NC05: Chemistry, Physics and Materials\u00a0Member of the Scientific Committee of the Canadian Fund for Innovation (CFI), Leaders Opportunity Fund with topics related to Materials Science.\u00a0Expert\/Examiner for the NSERC Discovery Grant Program.\u00a0External Examiner for the Ph.D. thesis of Mr. Hao Zhang \u201cNovel Phases on Hetero-Epitaxial and Super-Oxygenated Thin Films of Complex Oxides\u201d, Physics Department, University of Toronto, Avril 2018\u00a0External Examiner for the Ph.D. thesis of Mrs. Deepa Singh, Materials Science & Eng. , IIT-Kanpur, India, \u201cApproaches for improving ferroelectric properties of P(VDF-TrFE) for flexible memory devices\u201d, August 2016.\u00a0External Examiner for the Ph.D. thesis of Mrs. Olga Chichvarina, Materials Science & Eng., National University of Singapore (NUS) \u201cStudy of Structure and Properties of Oxide Electrode Materials (Fe3O4, AZO, SRO) and their Device Applications\u201d, Avril 2016.\u00a0\u00a0Associate editor, The European Physical Journal of Applied Physics\u00a0\u00a0Regular Reviewer for:Applied Physics Letter, Physical review B, Physical Review Letters, Journal of Applied Physics, Applied Physics A, Thin Solid Films, Functional Materials Letters, Microelectronic Engineering, Journal of Materials Science: Materials in Electronics, Journal of Materials Chemistry C\" \/>\n<meta name=\"robots\" content=\"noindex, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<meta property=\"og:locale\" content=\"en_US\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Alain Pignolet | INRS\" \/>\n<meta property=\"og:description\" content=\"Research project for a master\u2019s or a PhD student in Smart Materials :Next generation smart nanomaterials\u00a0(PDF)\u00a0\u00a0\u00a0Research Interests\u00a0Professor Pignolet works in the field of synthesis and characterization of thin films, heterostructures and nanostructures of new functional materials and their potential applications to micro- and nanoelectronics, as well as to generation, conversion and storage.

He also contributed to the advancement of piezoelectric force microscopy which enables imaging and characterization of the piezoelectric and ferroelectric properties at the nanoscale.Alain Pignolet earned a Bachelor degree in Engineering Physics and his Ph.D. in Physics from \u00c9cole Polytechnique F\u00e9d\u00e9rale de Lausanne (EPFL), Switzerland. 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, The Pennsylvania State University, to continue his research, working mainly with Pulsed Laser Deposition (PLD), reactive multi-target magnetron and ion-beam sputtering. From October 1994 to December 2001, Dr. Pignolet has hold a Research Staff Position at Max-Planck-Institut f\u00fcr Mikrostrukturphysik (Halle\/Saale, Germany) setting up a laboratory for deposition of ferroelectric thin films using large area PLD, as well as working on the optimization and better understanding of piezoresponse force microscopy.Professor Pignolet\u2019s present research interests and ongoing activities include the growth and studies of epitaxial thin films and nanostructures of functional materials such as ferroelectric, multiferroic, magnetic, magneto-optic or magnetoelectric materials for application in micro- and nano-electronics and integrated photonics. He has a particular interest for novel room temperature multiferroic and magnetoelectric materials.In particular, he has investigated the growth of multiferroic nanocomposite heterostructures, such as epitaxial magnetic g-Fe2O3 and ferroelectric BiFeO3 composite films, as well as epitaxial composites films of magnetic BaFe12019 and ferroelectric Ba2LnFeNb4O15 (Ln = Eu, Nd, Sm). Professor Pignolet\u2019s team was also the first to report the growth and characterization of epitaxial thin films of Bi\u00ad2FeCrO6 (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 epitaxial thin films and nanostructures exhibit multiferroic properties at room temperature, exceeding the theoretical predictions.Similarly, epitaxial strains have also been used to stabilize the metastable epsilon phase of ferrite (\u03b5-Fe2O3), a hard magnetic material potentially multiferroic at room temperature, in addition to possess the largest coercive field among oxides and to exhibit a magnetic resonance frequency in the low THz range.\u00a0 \u03b5-Fe2O3 epitaxial films therefore exhibit, in a single material, a number of properties of interest for various applications.\u00a0\u00a0Scientific Activities\u00a0Member of the FRQNT multidisciplinary \u00e9valuation committee NC05: Chemistry, Physics and Materials\u00a0Member of the Scientific Committee of the Canadian Fund for Innovation (CFI), Leaders Opportunity Fund with topics related to Materials Science.\u00a0Expert\/Examiner for the NSERC Discovery Grant Program.\u00a0External Examiner for the Ph.D. thesis of Mr. Hao Zhang \u201cNovel Phases on Hetero-Epitaxial and Super-Oxygenated Thin Films of Complex Oxides\u201d, Physics Department, University of Toronto, Avril 2018\u00a0External Examiner for the Ph.D. thesis of Mrs. Deepa Singh, Materials Science & Eng. , IIT-Kanpur, India, \u201cApproaches for improving ferroelectric properties of P(VDF-TrFE) for flexible memory devices\u201d, August 2016.\u00a0External Examiner for the Ph.D. thesis of Mrs. Olga Chichvarina, Materials Science & Eng., National University of Singapore (NUS) \u201cStudy of Structure and Properties of Oxide Electrode Materials (Fe3O4, AZO, SRO) and their Device Applications\u201d, Avril 2016.\u00a0\u00a0Associate editor, The European Physical Journal of Applied Physics\u00a0\u00a0Regular Reviewer for:Applied Physics Letter, Physical review B, Physical Review Letters, Journal of Applied Physics, Applied Physics A, Thin Solid Films, Functional Materials Letters, Microelectronic Engineering, Journal of Materials Science: Materials in Electronics, Journal of Materials Chemistry C\" \/>\n<meta property=\"og:url\" content=\"https:\/\/dev.inrs.ca\/en\/research\/professors\/alain-pignolet\/\" \/>\n<meta property=\"og:site_name\" content=\"INRS\" \/>\n<meta property=\"article:publisher\" content=\"https:\/\/www.facebook.com\/inrsciences\/\" \/>\n<meta property=\"article:modified_time\" content=\"2021-05-31T20:49:45+00:00\" \/>\n<meta property=\"og:image\" content=\"https:\/\/dev.inrs.ca\/wp-content\/uploads\/2020\/04\/Pignolet_Alain-1.jpg\" \/>\n\t<meta property=\"og:image:width\" content=\"900\" \/>\n\t<meta property=\"og:image:height\" content=\"708\" \/>\n\t<meta property=\"og:image:type\" content=\"image\/jpeg\" \/>\n<meta name=\"twitter:card\" content=\"summary_large_image\" \/>\n<meta name=\"twitter:site\" content=\"@inrsciences\" \/>\n<script type=\"application\/ld+json\" class=\"yoast-schema-graph\">{\"@context\":\"https:\/\/schema.org\",\"@graph\":[{\"@type\":\"WebPage\",\"@id\":\"https:\/\/dev.inrs.ca\/en\/research\/professors\/alain-pignolet\/\",\"url\":\"https:\/\/dev.inrs.ca\/en\/research\/professors\/alain-pignolet\/\",\"name\":\"Alain Pignolet | INRS\",\"isPartOf\":{\"@id\":\"https:\/\/dev.inrs.ca\/en\/#website\"},\"primaryImageOfPage\":{\"@id\":\"https:\/\/dev.inrs.ca\/en\/research\/professors\/alain-pignolet\/#primaryimage\"},\"image\":{\"@id\":\"https:\/\/dev.inrs.ca\/en\/research\/professors\/alain-pignolet\/#primaryimage\"},\"thumbnailUrl\":\"https:\/\/dev.inrs.ca\/wp-content\/uploads\/2020\/04\/Pignolet_Alain-1.jpg\",\"datePublished\":\"2020-08-04T19:56:58+00:00\",\"dateModified\":\"2021-05-31T20:49:45+00:00\",\"description\":\"Research project for a master\u2019s or a PhD student in Smart Materials :Next generation smart nanomaterials\u00a0(PDF)\u00a0\u00a0\u00a0Research Interests\u00a0Professor Pignolet works in the field of synthesis and characterization of thin films, heterostructures and nanostructures of new functional materials and their potential applications to micro- and nanoelectronics, as well as to generation, conversion and storage.

With over hundred publications in peer-reviewed journals, 3 book chapters and over 1500 citations, Dr. Pignolet has been on the forefront of research into synthesis and characterization of thin films and nanostructures of advanced functional materialssuch as ferroelectric, ferroic, and multiferroic oxides. He also contributed to the advancement of piezoelectric force microscopy which enables imaging and characterization of the piezoelectric and ferroelectric properties at the nanoscale.Alain Pignolet earned a Bachelor degree in Engineering Physics and his Ph.D. in Physics from \u00c9cole Polytechnique F\u00e9d\u00e9rale de Lausanne (EPFL), Switzerland. 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, The Pennsylvania State University, to continue his research, working mainly with Pulsed Laser Deposition (PLD), reactive multi-target magnetron and ion-beam sputtering. From October 1994 to December 2001, Dr. Pignolet has hold a Research Staff Position at Max-Planck-Institut f\u00fcr Mikrostrukturphysik (Halle\/Saale, Germany) setting up a laboratory for deposition of ferroelectric thin films using large area PLD, as well as working on the optimization and better understanding of piezoresponse force microscopy.Professor Pignolet\u2019s present research interests and ongoing activities include the growth and studies of epitaxial thin films and nanostructures of functional materials such as ferroelectric, multiferroic, magnetic, magneto-optic or magnetoelectric materials for application in micro- and nano-electronics and integrated photonics. He has a particular interest for novel room temperature multiferroic and magnetoelectric materials.In particular, he has investigated the growth of multiferroic nanocomposite heterostructures, such as epitaxial magnetic g-Fe2O3 and ferroelectric BiFeO3 composite films, as well as epitaxial composites films of magnetic BaFe12019 and ferroelectric Ba2LnFeNb4O15 (Ln = Eu, Nd, Sm). Professor Pignolet\u2019s team was also the first to report the growth and characterization of epitaxial thin films of Bi\u00ad2FeCrO6 (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 epitaxial thin films and nanostructures exhibit multiferroic properties at room temperature, exceeding the theoretical predictions.Similarly, epitaxial strains have also been used to stabilize the metastable epsilon phase of ferrite (\u03b5-Fe2O3), a hard magnetic material potentially multiferroic at room temperature, in addition to possess the largest coercive field among oxides and to exhibit a magnetic resonance frequency in the low THz range.\u00a0 \u03b5-Fe2O3 epitaxial films therefore exhibit, in a single material, a number of properties of interest for various applications.\u00a0\u00a0Scientific Activities\u00a0Member of the FRQNT multidisciplinary \u00e9valuation committee NC05: Chemistry, Physics and
