Researchers produce electricity by flowing water over extremely thin layers of metal
Aug 05, 2019 (SPX)
The films have a conducting metal nanolayer (10 to 20 nanometers thick) that is insulated with an oxide layer (2 nanometers thick). Current is generated when pu...
Quantum light sources pave the way for optical circuits
Aug 05, 2019 (SPX)
Previous circuits on chips rely on electrons as the information carriers. In the future, photons which transmit information at the speed of light will be able t...
Extraordinarily thick organic light-emitting diodes solve nagging issues
Jul 31, 2019 (SPX)
