C2N best wishes
Our teams wish you a very happy new year
Research
The centre develops research in the fields of material science, nanophotonics, nanoelectronics, nanobiotechnologies and microsystems, as well as in nanotechnologies. Its research activites cover all the range from fondamental to applied science.
The scientific project revolves around 10 major scientific challenges which are common to the 4 departments and federate research within the laboratory.
Jobs
Each year, researchers, engineers and technicians from around the world apply for CNRS or Paris-Saclay University positions to carry out their activity at C2N.
A number of internship, PhD position and Post-doc opportunities are also open at C2N.
Facility
The C2N gathers 3 plateforms into the Technology Facility and 3 platforms of expertise in instrumentation and characterization (optical and multiphysics).
The C2N Technology Facility belongs to the national nanofabrication network (Renatech network).
