gallium nitride

Graphene hogs all the headlines about two-dimensional materials, but it might just be the beginning. Researchers have now isolated a 2D form of the soft metal gallium, dubbed "gallenene," which could make for efficient, thin metal contacts in electronic devices.

Scientists have created a solar cell of mutiple layers of different perovskite materials that has a claimed a peak efficiency of 26 percent. And can usefully convert light energy over much greater parts of the spectrum than standard silicon solar cells.

Researchers from the Fraunhofer Institute for Applied Solid State Physics have announced a new advance in gallium nitride transistors that could help make the light-emitting diode (LED) the commercial light source of the future.
