PHOTON SCIENCE

Blends of synthetic polymers and diblock copolymers show a variety of morphologies. The selective interaction of metal atoms with organic layers due to different diffusivities and chemical interactions creates hierarchical nanostructures during deposition. Because of these excellent properties, I choose synthetic polymers and physical vapor deposition, especially sputter coating as a widely used fast deposition technology to fabricate highest density electrical contacts and nanocluster layers for storage media. The possibilities of scattering methods at DESY allow to elucidate the complex metal-polymer interface formation with high time resolution during the coating process. Sputter deposition at oblique deposition angles (GLAD) enables the fabrication of optically anisotropic materials and with tailored porosity via shadow effects, such as nanoantennas. Plasmonic properties, optical reflectivity and refractive indices can be tailored for novel sensing and energy applications. They require an understanding of how plasmonic properties interact with surrounding complex dielectric media, such as diblock copolymer thin films. For energy applications, the understanding of the nanoscale changes during the operation of energy harvesting and storage devices (long-term stability) leading to efficiency degradation is fundamental here.
Ultimately, our vision is to create and use a recyclable, CNF-based, flexible electronic device made from recycle base materials perfectly adapted to circular bioeconomy.
