Metasurfaces are two-dimensional (2D), nanoengineered surfaces that interact strongly with electromagnetic waves and can control light with remarkable precision. These ultra-thin layers can be used to ...

a, structure of LED based on PeNCs without and with passivation. Schematic illustrates that CP could passivate defects, in which the defects may trap carriers (e.g. holes, electrons), decrease exciton ...

Light is an unusually rich carrier of information. Its direction of travel, wavelength, and polarization can all be used to encode signals or images ...

a. A typical scenario in which complex targets with different spectral and polarization information in low-illumination background need to be distinguished by airborne or spaceborne payloads. b. In ...
