Chiral metasurfaces can strongly twist the polarization of light, but how this process unfolds in space and time has been unclear. Scientists in China have now used ultrafast electron microscopy and ...

This “heterostructure” consists of a stack of multiple different thin films, including a collection of aligned carbon nanotubes with different orientations. Credit: University of Utah This ...

Engineers have developed a multifunctional, reconfigurable component for an optical computing system that could be a game changer in electronics. As fast as modern electronics have become, they could ...

A new single-layer chiral metasurface detects circularly polarized light efficiently, offering a compact, high-performance alternative to bulky optical systems. (Nanowerk News) Detecting circularly ...

Forget LEDs, researchers from the University of Michigan have developed a new type of incandescent light bulb. The device is capable of emitting elliptically polarized light, described as "twisted" ...

When circular polarized light is irradiated onto a thallium lead alloy, the majority “up spins” of electrons flow in the right direction (spin-polarized current). Researchers Ibuki Taniuchi, Ryota ...

Researchers have demonstrated that the direction of the spin-polarized current can be restricted to only one direction in a single-atom layer of a thallium-lead alloys when irradiated at room ...

(Nanowerk News) Researchers Ibuki Taniuchi, Ryota Akiyama, Rei Hobara, and Shuji Hasegawa of the University of Tokyo have demonstrated that the direction of the spin-polarized current can be ...
