Epitaxial MgSnN2 on 4H‐SiC (0001): An Earth‐Abundant Nitride for Green Optoelectronics and Photovoltaics

Advanced Optical Materials, EarlyView.
The importance of photovoltaics (PV) and optoelectronics based on new Earth‐abundant materials is increasing with the ever‐growing energy demand and the need to address it with sustainable material technology. The paper demonstrates good quality magnetron sputter epitaxy of the inexpensive and eco‐friendly semiconductor MgSnN2 for green gap ...

Bismuth Nanogratings With Narrow Plasmon Resonances for Dynamic Polarized Color Generation and Colorimetric Sensing

Advanced Optical Materials, EarlyView.
Bismuth nanogratings are fabricated by pulsed laser deposition onto the nanostructured silver and polycarbonate surfaces of DVDs. They display spectrally‐narrow plasmon resonances yielding vivid colors, which are strongly sensitive to the polarization of light, angle of incidence, nature of the underlying surface and of the surrounding medium (air or ...

Scalable Design and Optimization of Reconfigurable Sb2S3 Metasurfaces

Advanced Optical Materials, EarlyView.
Scalable optimization methodologies are developed for reconfigurable Sb2S3 Huygens metasurfaces by combining localized phase‐match and overlap‐integral cost functions that account for inter‐element coupling. The framework enables computationally efficient design of large‐area, dual‐state flat optical devices with arbitrary wavefront transformations ...
