National University of Singapore scientists have demonstrated the non-invasive imaging of both the organic layers and underlying inorganic lattice of two-dimensional (2D) hybrid perovskites at the sub-angstrom level.
A photodetector is a kind of optoelectronic device that can detect optical signals and convert them into electrical signals. These devices include photodiodes, phototransistors and photoconductors.
The emerging field of valleytronics, which exploits the momentum preference of excited electrons, or excitons, in a variety of optoelectronic devices, is closely tied to the fabrication of novel 2D materials just atoms thick. ...
The demand for real-time health monitoring is growing. A research team from the Institute of Chemistry of the Chinese Academy of Sciences (ICCAS) recently developed a living material for real-time monitoring of lactate, a ...
Optics researchers at The University of Texas at Dallas have shown for the first time that a new method for manufacturing ultrathin semiconductors yields material in which excitons survive up to 100 times longer than in materials ...
A new publication from Opto-Electronic Advances discusses how deep learning makes single-shot, high-resolution structured light 3D imaging possible.
Recently, researchers in Shanghai Institute of Optics and Fine Mechanics (SIOM) of the Chinese Academy of Sciences carried out a systematic investigation on the microscopic optical nonlinearities and transient carrier dynamics ...
Carbon dots (CDs) are new carbon-based photoluminescence (PL) nanomaterials with a core-shell motif. Due to their fascinating advantages, such as chemical inertness, high quantum yields (QYs), high water solubility, thermal ...
The library of two-dimensional (2D) layered materials keeps growing, from basic 2D materials to metal chalcogenides. Unlike their bulk counterparts, 2D layered materials possess novel features that offer great potential in ...
Single-molecule electronic devices, which use single molecules or molecular monolayers as their conductive channels, offer a new strategy to resolve the miniaturization and functionalization bottlenecks encountered by traditional ...
