个人简介
My research interests (1982-1992) covered physics and characterization of point defects in semiconductors and devices, physics and reliability of thin insulating films, hot-carrier effects in MOSFETs. Since 1992, I am engaged in the field of electronic properties of molecular nanostructures and molecular electronics.
I am the author or co-author of more than 230 scientific (peer-reviewed) papers and 75 invited talks in international conference in these fields. I was scientific advisor for industrial companies (Bull R&D center) on advanced CMOS technology reliability (1988-1990) and for the CEA (Commissariat à l’énergie atomique et aux énergies alternatives) for the “Chimtronique” (Chemistry for nanoelectronics) research program (2006-2013).
I am mainly interested in the study of various molecular nanostructures and devices made of functional molecules (photoswitch, redox, magnetic,…) and 2D materials. I focus on their electronic properties at the nanoscale with the aim to contribute to the fundamental understandings of these systems. Characterization tools to study electron, spin and heat transport properties include various scanning probe microscopes (C-AFM, EFM, STM, SThM, SMM,…) as well as macroscopic soft electrical contact techniques on self-assembled monolayers (Hg, eGaIn contacts). Recent main results include:
– first demonstration of a molecular diode operating at 17 GHz (using interferometric scanning microwave microscope);
– role and determination of the π-π intermolecular interaction energies in molecular junctions;
– electron transport in molecular devices based on polyoxometalates, peptides, molecular switches (optical, ion,…), Prussian blue analog, assembled on various electrode materials (Si, metal, ferromagnet);
– thermal transport at the nanoscale (SThM : scanning thermal microscope) of molecular nanostructures made of BTBT derivatives and other molecules.
On an application-driven perspective, I contributed to the study of self-assembled monolayers (SAM) as: (i) nanodielectric in nano-scale OTFT, (ii) nanodielectric and charge transport layer in SAMFET, (iii) functionalized layers for gas sensors and optimization of organic device performances. I also contributed to the understanding of organic semiconductor doping mechanisms and electron transport properties of n-type oxide semiconductors (IGZO) for flexible transistors.
