of organic and molecular electronics. He has also a large experience in nanostructures fabrication (e-beam and UV lithography, etching\u2026), physical characterizations (AFM, XPS-UPS, spectroscopy UV-vis and FTIR) and electrical characterizations at the macro-scale (I-V 4K to 300K, C-V\u2026) and at nano-scale by scanning probe microscopes (STM, C-AFM, EFM, KPFM\u2026).<\/p>\n<p>St\u00e9phane Lenfant contributes in the NCM group at IEMN-CNRS, to the integration and the electrical characterization of molecular junctions with self-assembled monolayers grafted on gold or silicon surfaces. He coordinated the SYNAPTOR project (ANR 2014-2016) that has explored the integration of optical and switchable molecules for neuromorphic computing. He has participated to several national and European projects (currently HARVESTER ANR 2017-2021 and SPINFUN ANR 2018-2020). In addition to his scientific contribution in different WPs, he will manage the project (report writing, meetings organization\u2026).<\/p>\n<p>He has also been an active expert in the OMNT network dedicated to molecular electronics (2017). His current research on light switchable molecules (with azobenzene or diarylethene) includes material investigation (chemical\/ physical properties) to grafting, integration, and characterization of the related devices (from macroscopic surface contact to the nanoscale).<\/p>\n<p style=\"text-align: right\"><a href=\"https:\/\/cv.hal.science\/stephane-lenfant\">https:\/\/cv.hal.science\/stephane-lenfant<\/a><br \/>\n<a href=\"https:\/\/orcid.org\/0000-0002-6857-8752\" target=\"_blank\" rel=\"noopener noreferrer\">ORCID ID: 0000-0002-6857-8752<\/a><br \/>\n<a href=\"https:\/\/scholar.google.com\/citations?sortby=pubdate&amp;hl=en&amp;user=1UsMywMAAAAJ&amp;view_op=list_works\" target=\"_blank\" rel=\"noopener noreferrer\">\u00a0Google Scholar<\/a><\/p>\n<\/div><\/section><br \/>\n<section  class='av_textblock_section av-lyfkgize-67e843edd146e67cb3c4696355b6cb2a'   itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/CreativeWork\" ><div class='avia_textblock'  itemprop=\"text\" ><p><strong>Current research interests<\/strong><\/p>\n<ul>\n<li>Scanning probe microscope in electric mode (Conducting-AFM, KPFM, EFM)<\/li>\n<li>Integration and electrical characterization of self-assembled monolayers<\/li>\n<li>Functionalizationand surface characterizations<\/li>\n<li>Electronic properties of light switchable molecules deposited in self-assembled monolayers<\/li>\n<\/ul>\n<p><strong>Current project activities<\/strong><\/p>\n<ul>\n<li>Spintronics with functional molecules (SPINFUN)<br \/>\nANR, 2018-2021.<\/li>\n<li>Harvesting energy with polymer based thermoelectric generator to power autonomous sensors (HARVESTERS)<br \/>\nANR, 2017-2021. <a href=\"https:\/\/anr.fr\/Project-ANR-16-CE05-0029\" target=\"_blank\" rel=\"noopener noreferrer\">https:\/\/anr.fr\/Project-ANR-16-CE05-0029<\/a><\/li>\n<\/ul>\n<p><strong>Five selected publications<\/strong><\/p>\n<ul>\n<li>Conductance switching at the nanoscale of diarylethene derivatives self-assembled monolayers on La0.7Sr0.3MnO3<br \/>\nTHOMAS L., GUERIN D., QUINARD B., JACQUET E., MATTANA R., SENEOR P., VUILLAUME D., MELIN T., LENFANT S.<br \/>\nNanoscale (2020) (in press)<br \/>\ndoi: <a href=\"https:\/\/doi.org\/10.1039\/C9NR09928J\" target=\"_blank\" rel=\"noopener noreferrer\">10.1039\/C9NR09928J<\/a> (<a href=\"https:\/\/arxiv.org\/abs\/2003.09622\" target=\"_blank\" rel=\"noopener noreferrer\">arXiv<\/a>)<\/li>\n<li>Physical mechanisms involved in the formation and operation of memory devices based on a monolayer of gold nanoparticle-polythiophene hybrid materials<br \/>\nZHANG T.C., GUERIN D., ALIBART F., TROADEC D., HOURLIER D., PATRIARCHE G., YASSIN A., O\u00c7AFRAIN M., BLANCHARD P., RONCALI J., VUILLAUME D., LMIMOUNI K., LENFANT S.<br \/>\nNanoscale Adv. 1, 7 (2019) 2718-2726<br \/>\ndoi: <a href=\"https:\/\/doi.org\/10.1039\/C9NA00285E\" target=\"_blank\" rel=\"noopener noreferrer\">10.1039\/C9NA00285E<\/a> (<a href=\"https:\/\/arxiv.org\/abs\/1905.12719\" target=\"_blank\" rel=\"noopener noreferrer\">arXiv<\/a>) (<a href=\"https:\/\/hal.archives-ouvertes.fr\/hal-02182920\/\" target=\"_blank\" rel=\"noopener noreferrer\">hal-02182920<\/a>)<\/li>\n<li>Negative Differential Resistance, Memory and Reconfigurable Logic Functions based on Monolayer Devices derived from Gold Nanoparticles functionalized with Electropolymerizable Thiophene-EDOT units<br \/>\nT.
