NanoLund Photons Meeting: "Fabrication of 3D architected structures by metasurface enabled holographic lithography"
Matias Kagias will give a seminar. Matias is assistant professor at Synchrotron Radiation Research.
Abstract:
Architectural control at the meso and nanoscale has emerged as a powerful tool for engineering materials with unique and superior macroscopic properties. Notable demonstrations range from structures with ultra-high specific strength to materials with negative refractive index. Fabrication of such 3D geometries with a high design freedom and scalability represents a significant challenge for state-of-the-art micro-nanofabrication methods. Optical metasurfaces can generate high contrast complex 3D illumination pattens that can be printed in photosensitive polymers. This enables a facile and scalable approach for holographic lithography that is capable of patterning centimeter scale areas with mesoscale features. In this talk, I will report on the development of metasurface enabled lithography and further discuss morphological characterization of the resulting 3D architected structures.
