报告摘要：
Harvesting the behavior of charges, excitons and photons is highly desired for the next generation of optoelectronic, photovoltaic and photonic devices. It can be achieved by engineering one dimensional nano-architectures. Latest improvements in the fabrication methods permit the design of nanowires and nanotubes with improved features or with more complex architectures, including coaxial, (multi-)segmented, hybrid and composite systems. Consequently, it is possible to control and to tune their properties, as well as to reach new behaviors and multifunctionality. The wide range of source materials, electrical and optical behavior and tunable surface functionalities make these systems very promising for chemical and bio-sensors, organic electronics, supercapacitor, photovoltaic cells, electrochromic devices.
I will review our recent studies of (conjugated) polymer-based nanowires and nanotubes prepared by the template method. The relation between the nanoscale and the unique electrical, optical, optoelectronic and photonic properties will be emphasized. [1-5]

报告人简介:
Prof. Jean-Luc Duvail received a B.S. in physics in 1991 and a Ph.D. in Materials Physics under supervision of professor A. Fert (Nobel Prize in Physics, 2007) from University of Orsay Paris-XI, France. He did postdoctoral research with professor L. Piraux at Université Catholique de Louvain, Belgium before joining the faculty at the University of Nantes in 1998. He is currently professor and Nanowire group leader at the Institut des Matériaux Jean Rouxel in Nantes, France.
His main research interest is in the area of one-dimensional nanostructures made of conjugated or non conjugated polymer, metals, carbon nanotubes and hybrids, in relation with optoelectronics and nanophotonics applications. He is author or co-author of more than 70 articles, 5 book chapters.
