Over the past decade, organic luminescent materials have been recognized by academia and industry alike as promising components for light, flexible and versatile optoelectronic devices such as OLED displays. However, it is ...
The world's best tandem solar cells consisting of a silicon bottom cell and a perovskite top cell can today convert about a third of the incident solar radiation into electrical energy. These are record values, especially ...
Halide perovskites are a family of materials that have attracted attention for their superior optoelectronic properties and potential applications in devices such as high-performance solar cells, light-emitting diodes, and ...
Since the scientists at Bell Labs invented the world's first transistor in December 1947, a revolution in microelectronics technology has profoundly affected lifestyles worldwide. As electronics get smaller and smaller, it ...
Passive mode-locked technology utilizes saturable absorbers' nonlinear absorption effect to regulate the cavity's loss and phase to generate mode-locked pulses. Graphene has a unique energy bandgap structure, a low absorption ...
A facile technique for reproducibly creating Swiss-cheese-like nanomaterials has been developed by researchers at KAUST. This material, and the method required to create it, could help in the development of further advanced ...
Some molecules exist in two forms, such that their structures and their mirror images are not superimposable, like our left and right hands. Called chirality, it is a property these molecules have due to their asymmetry. ...
A research group led by Prof. Wang Liping at the Ningbo Institute of Materials Technology and Engineering (NIMTE) of the Chinese Academy of Sciences has reported the enhanced oxygen reduction reaction (ORR) activity and biperiodic ...
When a photon interacts with a material, an interaction occurs that causes its atoms to change their quantum state (a description of the physical properties of nature at the atomic level). The resulting state is called, aptly, ...
Electrically pumped semiconductor lasers are among the most important sources, owing to their high efficiency, compactness, and solid-state stability. For mid-infrared and terahertz radiation, quantum cascade lasers (QCLs) ...
