Prof Denis FichouOur present research aims at conceiving novel materials, either organic or inorganic in nature, in view of energy applications such as sunlight conversion and storage. 1. Organic and hybrid photovoltaic cells We design and synthetize novel small organic molecules having an extended pi-electron system and use them either as active materials (p- or n-type semiconductors) or as interfacial layers in thin film solar cells. We recently developed series of molecules such as for example dipyrranylidenes and organo-cobalt complexes, that we used to fabricate efficient photovoltaic solar cells. 2. Oxide-based photoelectrochemical systems We aim at converting efficiently sunlight into clean and readily usable fuels such as hydrogen or methane on a large scale. One of the most promising technologies consists in splitting water into hydrogen and oxygen through solar irradiation of semiconductor-based devices. We recently designed various efficient PEC systems based on either WO3, Cu2O, or BiVO4 among others, and used them under sunlight illumination to produce hydrogen. 3. Supramolecular self-assemblies on surfaces The self-assembly of organic molecules on solid surfaces provides a versatile route towards functional 2D arrays in view of energy, catalytic and magnetic applications. Our group develops unique supramolecular architectures by controlling the size and shape of the molecular bricks. We then observe and manipulate the assemblies at the atomic/molecular scale by means of scanning tunneling microscopy (STM).
Prof Gan Chee LipA/Prof Gan's research area is on microelectronics interconnect systems, spanning from reliability of conventional Cu/low-k interconnects, to three-dimensional (3D) interconnects and nanowires interconnects. Dr Gan's current research interests include the reliability study of advanced interconnect systems, such as copper electromigration, time-dependent-dielectric-breakdown of low-k dielectrics and new assessment methodology for circuit level reliability projection. Another area of research is on the process integration and reliability of 3D interconnects through copper-copper wafer bonding. Fabrication of metallic nanowires by a template method as interconnects is also being investigated. Work is carried out to characterize the morphology and electrical properties of the nanowires to assess its suitability for actual applications.
