An exponential increase in the amount of stored information is making the development of new optoelectronic devices increasingly important. Recently, photonic crystals have emerged as an alternative to overcome the limitations ...
The researchers from Changchun Institute of Optics, Fine Mechanics and Â鶹ÒùÔºics of the Chinese Academy of Sciences and Peking University have developed a new technique for upgrading the quality of topological insulator bismuth ...
In traditional vision systems, the optical information is captured by a frame-based digital camera, and then the digital signal is processed afterwards using machine-learning algorithms. In this scenario, a large amount of ...
A new study led by Dai Qing's team from the National Center for Nanoscience and Technology (NCNST) of the Chinese Academy of Sciences (CAS) and Javier Abajo from the Institute of Photonic Sciences (ICFO) in Spain has shown ...
Â鶹ÒùÔºicists have been trying to identify reliable strategies to manipulate quantum states in solid-state materials, cold atoms and other systems, as this could inform the development of new technologies. One of these strategies ...
Quantum dots are semiconductor particles measuring just a few nanometers across, which are now widely studied for their intriguing electrical and optical properties. Through new research published in The European Â鶹ÒùÔºical ...
Bound electron-hole pairs, or excitons, are the workhorses in layered transition metal dichalcogenide semiconductors. Like the negative and positive charge carriers from which it forms, the exciton exhibits great mobility ...
Excitons are drawing attention as possible quantum bits (qubits) in tomorrow's quantum computers and are central to optoelectronics and energy-harvesting processes. However, these charge-neutral quasiparticles, which exist ...
Until now, it has been clear: you can have a metal or a plastic, but not both in one. However, things don't have to stay that way. In the journal Angewandte Chemie, a Chinese research team has now reported a polymer with ...
Van der Waals heterostructures integrated from various two-dimensional (2D) layered materials provide fundamental building blocks for optoelectronic devices with novel functionalities, such as photovoltaic solar cells, light ...
