Semiconductor Metamaterials: Part One, Volume 116 in a two-part series surveys the state-of-the-art in material platforms for optical metasurfaces. Chapters cover Metasurfaces from materials with 2nd-order nonlinearity, Light Emitting Metasurfaces based on Direct Bandgap Semiconductors, Tunable Metasurfaces enabled by Phase-Change Materials, Phase-Transition Materials for Thermal Tuning of Metasurfaces, Tunable Metasurface Devices based on Soft Matter, Infrared Metasurfaces, Polarization Sensing Platforms, UV/ Visible Metasurfaces, and Metasurfaces for Catalysis & Chemistry.

Dr. Martin Hafermann is a research associate at Friedrich Schiller University Jena where he explores the use of ion beams to modify various material platforms for enhanced optical applications. He earned his PhD in 2021 at FSU Jena investigating ion-beam modified phase-change materials for metasurfaces. Dr. Sarah Walden is a lecturer at Griffith University investigating tuneable nanophotonic devices using stimuli-responsive materials. In 2017 Sarah completed a PhD at the Queensland University of Technology (QUT), investigating the nonlinear optical properties of semiconductor nanoparticles. After her PhD, she became a Postdoctoral Fellow jointly between the Soft Matter Materials Laboratory at QUT and the Karlsruhe Institute of Technology (KIT), investigating new materials for photolithography. In 2022, Sarah commenced a Zukunfts Fellowship at the Friedrich Schiller University Jena, where she applied stimuli-responsive polymers for tuneable metasurface devices.
