A nanostructure made of silver and an atomically thin semiconductor layer can be turned into an ultrafast switching mirror device that may function as an optical transistor—with a switching speed ...

Researchers in Germany have unveiled an ultra-fast light switch made of very thin semiconductor layers, that runs around 10,000 times faster than today’s electronic transistors. Designed by a team of ...

Twenty years ago, a Duke University professor, David R. Smith, used artificial composite materials called “metamaterials” to make a real-life invisibility cloak. While this cloak didn’t really work ...

Using complex experimental set-ups, the researchers study the extremely fast movements of electrons in solids with laser pulses with a high degree of temporal resolution. A nanostructure made of ...

A team of physicists at the University of Oldenburg has demonstrated an ultra-fast switching process that could be used in optical components in the future. The researchers developed a light switch ...

Beyond their sparkle, diamonds have hidden talents. They shed heat better than any material, tolerate extreme temperatures and radiation, and handle high voltages while wasting almost no ...
