Abstract The advent of metamaterials, e.g. artificially structured materials with physical properties significantly distinct from their bulk counterparts, has ushered in new perspectives in materials science and photonics, and constitutes today a new research frontier. Tailored order at the micro- or nanoscale has unlocked a host of novel opportunities in fields such as harmonic generation, wavefront shaping, and biochemical detection and analysis. This progress has heavily relied on thin films, which constitutes fundamental building blocks for many micro- and nanoscale devices today. As dimensions of devices has shrunk, the question of thin film stability has become critical in numerous systems, given that their intrinsic high surface-to-volume ratio makes them particularly subject to instabilities. Such instabilities are potentially responsible for loss of percolation and disordered geometries, hence threatening both metamaterial integrity and functionality. In this talk, we investigate the possibility to guide pre-defined or “templated” instabilities in thin chalcogenide films to induce prescribed order at the micro and nanoscale through two distinct original processes, effectively providing a novel frame for scalable yet high performance optical devices in the visible to near-infrared.

Bio Louis Martin-Monier is a researcher at the Laboratory of Photonic Materials and Fiber Devices (FIMAP), within the department of Materials at EPFL. The topic of his PhD research deals with novel processing methods for the scalable development of metamaterials. His research interests include thin film dynamics, processing methods at the nanoscale, and development of 2D photonic devices based on tailored nanostructuring schemes.
He got his M.Sc from the École des Mines in Paris, France in 2016 with a specialization in Materials Science. In 2021, he graduated with a PhD also in Materials Science from EPFL.
