Weyl semimetals could be used to fabricate new photonic devices

Engineers have developed the thinnest optical waveguide in the world, comprising a tungsten disulfide monolayer suspended on a silicon frame.

Researchers have found a way to use 3D printing to stretch and flatten twisted conjugated polymers so that they conduct electricity better.

A thin film of polymer microspheres that reflects light in intriguing ways could be used to make road signs that shine brightly and change color at night.

By utilizing the quantum confinement effect, scientists have been able to produce perovskite-based LEDs with record-breaking brightness.

Researchers have discovered that the electrical properties of quantum materials known as Weyl semimetals can be controlled with light.

Treating perovskite solar cells with benzylamine to remove defects actually results in the formation of 2D material on the surface of the 3D crystal.

By combining thin organic layers with thick layers of hybrid perovskite, researchers have developed micrometer-thick organic light-emitting diodes.
