Physical phenomena with reduced dimensions


Several research groups focus on the physical properties unique to reduced dimensions and nano-objects, such as surfaces, nanostructures, molecules and atoms. We experimentally and theoretically investigate the magnetization dynamics of magnetic materials, the (quantum) electronic properties at low temperatures of mesoscopic circuits or individual molecules, the thermodynamics of surfaces or nanostructures, the dynamics of growth, photonic gaps and states in nano-photonic structures, the electromagnetic response and electronic structure of individual nano-objects. The characterization of individual or ensembles of nano-objects is achieved with complementary techniques : low-energy electron diffraction, high-energy electron spectroscopy and microscopy, X-Ray scattering, ion desorption by impact of very low energy electrons, and optical microscopy.
