Perovskites – materials of the future in optical communication

Researchers at the universities of Linköping and Shenzhen have shown how an inorganic perovskite can be made into a cheap and efficient photodetector that transfers both text and music. "It's a promising material for future ...

Extreme conditions in semiconductors

Scientists from the University of Konstanz and Paderborn University have succeeded in producing and demonstrating what is known as Wannier-Stark localization for the first time. In doing so, the physicists managed to overcome ...

Researchers boost performance quality of perovskites

Solar cells are devices that absorb photons from sunlight and convert their energy to move electrons—enabling the production of clean energy and providing a dependable route to help combat climate change. But most solar ...

Psst! A whispering gallery for light boosts solar cells

Trapping light with an optical version of a whispering gallery, researchers at the National Institute of Standards and Technology (NIST) have developed a nanoscale coating for solar cells that enables them to absorb about ...

Scientists have a new way to gauge the growth of nanowires

In a new study, researchers from the U.S. Department of Energy's (DOE) Argonne and Brookhaven National Laboratories observed the formation of two kinds of defects in individual nanowires, which are smaller in diameter than ...

A milestone in petahertz electronics

In a semiconductor, electrons can be excited by absorbing laser light. Advances in the past decade have enabled measuring this fundamental physical mechanism on timescales below a femtosecond (10-15 s). Now, physicists at ...
