Harnessing hot carriers for high efficiency solar cells

Two-dimensional solar materials may offer a way to extract more energy from sunlight. By tuning the structure of a 2-D perovskite solar material, researchers from KAUST and the Georgia Institute of Technology have shown they ...

Ultrafast stimulated emission microscopy of single nanocrystals

The ability to investigate the dynamics of single particle at the nano-scale and femtosecond level remained an unfathomed dream for years. It was not until the dawn of the 21st century that nanotechnology and femtoscience ...

Probing a nuclear clock transition

Modern atomic clocks are the most accurate measurement tools currently available. The best current instruments deviate by just one second in 30 billion years. However, even this extraordinary level of precision can be improved ...

Laser-produced uranium plasma evolves into more complex species

When energy is added to uranium under pressure, it creates a shock wave, and even a tiny sample will be vaporized like a small explosion. By using smaller, controlled explosions, physicists can test on a microscale in a safe ...

Detraction-free light-matter interaction

An efficient light-matter interface might constitute the foundation of quantum communication. However, certain structures that are formed during the growth process interfere with the signal.
