Quantum dots amplify light with electrical pumping

Researchers achieve light amplification with electrically stimulated quantum dots, critical step towards solution-processible laser diodes.

New way to write magnetic info could pave the way for hardware neural networks

Researchers have shown how to write any magnetic pattern desired onto nanowires, which could help computers mimic how the brain processes information.

'Unparalleled access' in surface science

Interdisciplinary research team wins NSF support for next-generation surface analysis.

Glass microparticles enhance solar cells efficiency

Researchers have suggested a new solar cell coating that combines features of an electrode and those of a light-trapping structure. The coating enabled them to cut down on reflected light and avoid solar cell overheating, thus increasing its overall efficiency by 20%.

Spin current from heat: New material increases efficiency

Electronic devices such as computers generate heat that mostly goes to waste. Physicists have found a way to use this energy: They apply the heat to generate magnetic signals known as 'spin currents'.
