Your Work Environment

CEMES-CNRS is a fundamental CNRS research laboratory specialized in solid-state physics, nanoscience, molecular chemistry, and materials science of approximately 150 people distributed across 7 research groups and 4 technical platforms.

It has a 400 m² cleanroom dedicated to micro- and nanofabrication. This cleanroom is equipped with optical, laser, and electron beam lithography techniques, wet and dry etching, as well as a focused ion beam (FIB) system. It also allows for electron beam metallization and the deposition of passivation layers. Morphological characterization equipment, including atomic force microscopy, along with electrical and optical characterization tools, complement these technological resources.
The ANR MetaCharge project aims to exploit nanofabricated magnetic metamaterials as experimental platforms to emulate and visualize, in real time and at the nanoscale, fundamental charge transport phenomena. By using two-dimensional arrays of nanomagnets, the project aims to establish a link between frustrated magnetism and the physics of electron transport. The success of this project depends crucially on the controlled fabrication of thermally active metamaterials compatible with advanced operando imaging techniques, particularly transmission electron microscopy (TEM).
