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 ...).
