Two research reports offer insight into the type of commitment required to get—and stay—ahead of a seemingly intractable problem.

Researchers in Spain create nontoxic colloidal quantum dots that preserve the advantageous properties of their heavy-metal counterparts—and use them in high-performance SWIR photodetect...

Researchers in South Korea demonstrate light amplification via chemically synthesized perovskite nanosheets—a new laser medium.

A higher quality edge, without compromising speed or efficiencies, provides promise for new applications.

Compared to electrical detection, an all-optical ultrafast laser technique provides the resolution needed to explore electron transport within ballistic and coherent regimes.
