Gate-Variable Mid-Infrared Optical Transitions in a Topological Insulator
William S. Whitney, Victor W. Brar, Yunbo Ou +6
We report mid-infrared spectroscopy measurements of an electrostatically gated topological insulator, in which we observe several percent modulation of transmittance and reflectanc…
Optical Magnetism in Planar Metamaterial Heterostructures
Georgia T. Papadakis, Dagny Fleischman, Artur Davoyan +2
Harnessing artificial optical magnetism requires rather complex two- and three-dimensional structures, examples include split-ring and fishnet metamaterials and nanoparticles with…
Near Unity Absorption in Van der Waals Semiconductors for Ultrathin Optoelectronics
Deep Jariwala, Artur R. Davoyan, Giulia Tagliabue +3
We demonstrate near unity, broadband absorbing optoelectronic devices using sub-15 nm thick transition metal dichalcogenides (TMDCs) of molybdenum and tungsten as van der Waals sem…
