Ultrathin, conductive films such as those made of graphene are widely used in modern optoelectronic devices, but it has been thought that their efficacy is fundamentally limited: they can absorb at ...

Thin film systems capable of absorbing light across a broad spectrum are a focal point of contemporary photonics research. These systems combine nanoscale engineering of dielectric and metallic layers ...

A new technical paper titled “Exploring Electrochemical Methods for Precision Stress Control in Nanoscale Devices ” was published by researchers at the University of Bristol. “Tuning the local film ...

Perfect absorption with adjustable Q factor and wavelength is essential in both theory and application. To address this issue, a structure composed of an epsilon-near-zero (ENZ)- SiO 2 grating and a ...

Metasurfaces make quantum dot films cooler where they emit more efficiently, turning light-controlled temperature gradients into self-powered electrical signals.
