DESCRIPTION:Louis Martin-Monier (FIMAP\, EPFL)\nAbstract The advent of m
 etamaterials\, e.g. artificially structured materials with physical proper
 ties significantly distinct from their bulk counterparts\, has ushered in 
 new perspectives in materials science and photonics\, and constitutes toda
 y a new research frontier. Tailored order at the micro- or nanoscale has u
 nlocked a host of novel opportunities in fields such as harmonic generatio
 n\, wavefront shaping\, and biochemical detection and analysis. This progr
 ess has heavily relied on thin films\, which constitutes fundamental build
 ing blocks for many micro- and nanoscale devices today. As dimensions of d
 evices has shrunk\, the question of thin film stability has become critica
 l 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 geomet
 ries\, hence threatening both metamaterial integrity and functionality. In
  this talk\, we investigate the possibility to guide pre-defined or “tem
 plated” instabilities in thin chalcogenide films to induce prescribed or
 der at the micro and nanoscale through two distinct original processes\, e
 ffectively providing a novel frame for scalable yet high performance optic
 al devices in the visible to near-infrared.\n\nBio Louis Martin-Monier is
  a researcher at the Laboratory of Photonic Materials and Fiber Devices (F
 IMAP)\, within the department of Materials at EPFL. The topic of his PhD r
 esearch deals with novel processing methods for the scalable development o
 f metamaterials. His research interests include thin film dynamics\, proce
 ssing methods at the nanoscale\, and development of 2D photonic devices ba
 sed on tailored nanostructuring schemes.\nHe got his M.Sc from the École 
 des Mines in Paris\, France in 2016 with a specialization in Materials Sci
 ence. In 2021\, he graduated with a PhD also in Materials Science from EPF
