  Future optics and electronics

Optical field around a gold 40 nm in diameter and 4 microns in length nano rod, induced by an incident laser wave. (Équipe LEPO).

Future optics and electronics :  Building a device (electronic, magnetic, photonic, sensor ...) at the atomic scale (nanometer) is the final step in miniaturization. In the laboratory nanofabrication techniques allow to carry out individual structures of a few atoms or molecules.

Beyond the reduction in size and the resulting increase in integration density,  new properties appears at  this scale, often of quantum origin, which can be used. Understanding the behavior of these "nano-objects", controlling their fabrication process or integration in devices and studying their properties are research topics carrying industrial issues for tomorrow.

The action of IRAMIS on the subject is facing a fundamental knowledge of the behavior of atomic or molecular systems and the search for new applications yet unimagined. An important activity of the IRAMIS concerns spin electronics (spintronics), with in particular the design and production of ultra-sensitive magnetic field sensors with multiple applications (non-destructive testing, security, speed sensors, sensors current ...).

Research topics
Several IRAMIS teams are involved in calculations of the electronic structure (ab-initio , tight binding, Hückel methods, etc...) and more generally in the modeling of matter at the atomic scale, which also includes more phenomenological methods (empirical potentials, model Hamiltonians, etc...
Mastering light / matter interactions at scales smaller than the wavelength
Photonics is the science and technology of the production of photons, their propagation and their absorption by matter. The photonic properties of condensed matter depends on the intrinsic properties of its constituents (molecules, crystalline lattice,...
With organic and molecular electronics, a data processing based on various types of nano-objects (molecules, biomolecules, nanoparticles, carbon nanotubes, graphene,...) is emerging.
