German researchers film graphene electrons jumping with laser pulses
A team from the University of Regensburg and partners watched electrons jump across an energy gap in graphene using laser light, published in Nature.
Scientists used laser light to watch tiny particles jump between two energy levels. This could one day help build faster devices, but the road is still long.

Why it matters
Understanding how light steers electrons may one day open a path to faster electronics, but this is still basic research.
Watch: exciting science, but far from products.
The details
- Researchers from the University of Regensburg, the University of Marburg and Forschungszentrum Jülich took part; the result is in Nature.
- The team used intense laser pulses to push electrons across an energy gap they normally cannot occupy.
- When the light was strong enough, the jump probability reached 100%.
- The test used ultra-pure graphene one atom thick, tracked with a microscope that measures electron energy and motion.
- The authors say it could help high-speed semiconductors, but there is no device or commercial date.
