Nanoelectrochemistry: from the synthesis of nanomaterials to functionnality

Objective

The training site NANOELECTROCHEMISTRY is composed of 3 teams from 3 laboratories in the Paris area interconnected with fast public transportation. The active collaboration existing between the different partners forms an interdisciplinary network, with chemists and physicists joining efforts and experiences by putting together their know-how in nanosystems electrochemical synthesis, and their knowledge in electrochemistry and solid-state physics (magnetism, growth, optics). The research activities developed at the NANOELECTROCHEMISTRY tackle fundamental questions about model systems, which are easily transposable to systems with potential industrial applications. Researchers involved in NANOELECTROCHEMISTRY come from a broad scientific area, ensuring a rich and fertile environment for assisting the fellows. Their different scientific backgrounds and their detailed knowledge of their instruments (mainly home-build) provide varied and qualified technical inputs for the fellows, which is of prime importance for a mainly experimental work as that proposed here. Moreover, the home build instruments in this training site ensure them to be best suited for the experimental need, which is an important aspect for having a successful training period. The techniques used in NANOELECTROCHEMISTRY have the particularity of performing measurements in-site in the electrochemical environment. Their can be classified in 3 groups:
1) Morphologic characterization: scanning tunneling microscopy, atomic force microscopy
2) Magnetic characterization: Polar Magneto-Optical Kerr Effect and Alternating Gradient Field Magnetometry for measuring the magnetization of the magnetic layer with submonolayer resolution, and Scanning Near Field Optical Microscope for local characterization (submicrometer) of the magnetization.
3) Optical characterization: Infrared spectroscopy for identifying the organic molecules grafted on the Si surface and for investigating the optical properties of metallic nanoparticules. The AFM and the SNOM are as well used in the micro/nanomachining, the tip initiating the electrochemical nanostructuring in its vicinity via electrical nanopulse or local light injection.
