A dopant molecule accepts electrons from a chiral perovskite host, enabling visible light absorption while preserving the ...

The resulting material retains the handedness that makes chiral semiconductors promising building blocks for next-generation ...

Invisible infrared waves are emitted by IR LEDs and detected by photodiodes to enable devices like remotes, automatic washbasins to function; this ‘magic’ is actually optics and condensed matter ...

By harnessing the unique properties of tantala (tantalum pentoxide), a team of US-based researchers has created a photonic integrated circuit that can be tuned to deliver laser light across a broad ...
