Electrostatic Steering of Thermal Emission with Active Metasurface Control of Delocalized Modes
Joel Siegel, Shinho Kim, Margaret Fortman +6
We theoretically describe and experimentally demonstrate a graphene-integrated metasurface structure that enables electrically-tunable directional control of thermal emission. This…
Design parameters of free-form color routers for subwavelength pixelated CMOS image sensors
Sanmun Kim, Chanhyung Park, Shinho Kim +2
Metasurface-based color routers are emerging as next-generation optical components for image sensors, replacing classical color filters and microlens arrays. In this work, we repor…
Quantitative determination of optical and recombination losses in thin-film photovoltaic devices based on external quantum efficiency analysis
Akihiro Nakane, Hitoshi Tampo, Masato Tamakoshi +6
In developing photovoltaic devices with high efficiencies, quantitative determination of the carrier loss is crucial. In conventional solar-cell characterization techniques, howeve…
