Electrical engineers at Duke University have demonstrated the fastest pyroelectric photodetector to date, which works by absorbing heat generated by incoming light. Capable of capturing light from the entire electromagnetic ...
In recent years, van der Waals crystals have evolved from scientific curiosities into a versatile platform for exploring novel quantum phases and unconventional nanophotonic phenomena. Their layered nature allows stacking, ...
Adjusting the size and chemistry of nanocrystals within an ultrathin surface can speed up light-driven chemical reactions, according to a University of Michigan Engineering study published in the Journal of the American Chemical ...
When light passes through materials, it typically changes direction and bends in predictable ways. This change in direction, known as refraction, is caused by a change in the speed of light as it enters a new medium. In some ...
When we think about heat traveling through a material, we typically picture diffusive transport, a process that transfers heat from high-temperature to low-temperature as particles and molecules bump into each other, losing ...
Can we use nothing more than sunlight and inexpensive materials to produce clean hydrogen fuel while also removing toxic pollutants from water? That question shaped our recent work with γ-In2S3, a semiconductor that has intrigued ...
The global development of civilization diseases is a challenge that requires many modern solutions, not only in terms of treatment, but first and foremost in terms of early diagnostics. One of the highly sensitive methods ...
You can tell a lot about a material based on the type of light shining at it: Optical light illuminates a material's surface, while X-rays reveal its internal structures and infrared captures a material's radiating heat. ...
Researchers at the Institute for Molecular Science (NINS, Japan) and SOKENDAI have demonstrated a more than 2000% voltage-induced enhancement of near-field nonlinear optical responses. To achieve this giant modulation, they ...
By changing the physical structure of gold at the nanoscale, researchers can drastically change how the material interacts with light—and, as a result, its electronic and optical properties. This is shown by a study from ...
