Fabrication of Metasurfaces by Self-Assembly of Block Copolymers

This PhD position at Université Bordeaux 1, in collaboration with CEA-Leti, focuses on advancing material nanostructuring through the self-assembly of block copolymers. The successful candidate will investigate mixed block copolymer systems to generate multiple patterns in a single self-assembly step and utilize chemoepitaxy for precise spatial control. The research involves designing functionalized substrates via advanced lithography, conducting self-assembly experiments, and analyzing the resulting nanostructures using state-of-the-art metrology equipment. The project ultimately targets the creation of optical metasurfaces capable of manipulating light, reducing diffraction, and controlling polarization.
