How to Manufacture Photonic Metamaterials

Advanced Materials Technologies, EarlyView.
Metamaterials boast applications such as invisibility and “hyperlenses” with resolution beyond the diffraction limit, but these applications haven’t been exploited in earnest and the market for them hasn’t grown much likely because facile and economical methods for fabricating them without defect has not emerged.

Highly Efficient n‐Type Doped Single‐Crystalline Perylene Diimide Microwires via Solution Processing for High‐Performance Photosensors and Photo‐Neuromorphic Devices

Advanced Materials Technologies, EarlyView.
Solution‐processed high‐performance n‐type doped single‐crystalline organic semiconductor microwires (MWs) are reported. n‐Type dopants are located at the terrace edge of the MW, resulting in rapid doping and high interaction. n‐doped MWs show 5,000 times enhanced photosensitivity than evaporated films and high photo‐neuromorphic characteristics by ...
