Briefings

A Technion-led team successfully used laser pulses to control the direction of electron flow in a scanning tunneling microscope, enabling researchers to observe individual atoms and capture ultrafast electron motion. This breakthrough allows for precise manipulation of electron flow while maintaining nanoscale spatial resolution, marking a significant step in observing atomic-scale dynamics.

Key points

• Researchers used carefully shaped laser pulses to control the direction of electron flow in a scanning tunneling microscope.
• The study achieved simultaneous observation of individual atoms and capture of electron motion at ultrafast timescales.

Context

This research represents a major advancement in nanotechnology, allowing scientists to manipulate electron flow at the atomic level with high spatial resolution. The method combines advanced laser techniques with scanning tunneling microscopy to enable unprecedented observation of atomic-scale dynamics.

Limitations

The evidence is limited to a single published article from October 2026. Specific experimental parameters, such as exact laser pulse durations, material types used, or the number of atoms observed, are not provided in the source.
