Future devices will continue to probe the frontier of the very small, and at scales where functionality depends on mere atoms, even the tiniest flaw matters. Researchers at Rice University have shown ...

The applications of ultrathin, conductive films such as those made of graphene have many applications, but it's been thought their efficacy is limited to absorbing only half of the incidental light at ...

Researchers have identified a class of quantum materials, called topological semimetals, that can split water into hydrogen fuel using nothing but sunlight, sidestepping the expensive platinum-based ...

Photo-reflectance spectroscopy enhances semiconductor quality control with sensitive, contactless measurements of band structure and electric fields in devices.

Light can hit a lead halide perovskite crystal that is anything but pristine and still end up as useful electric current.

Abstract: This paper presents a frequency selective rasorber (FSR) with two wide passbands and an absorption band, based on a polarization converter. The proposed FSR structure, achieved by ...

Ruthenium-functionalized nanodiamonds generate powerful solvated electrons under visible light, bypassing the deep UV requirement that has limited diamond photocatalysis to laboratory settings.

Time marches on, but the urge to rock continues. Some iconic musicians are touring in their 70s and 80s these days, while others have retired and left the road behind. When a classic rock band comes ...

Abstract: In this work, we study a cross-band network which simultaneously utilizes optical wireless (OW) and radio frequency (RF). OW is used for the downlink scenario to simultaneously transmit ...
