Molecular dynamics in real time

A novel spectroscopic method allows ultrafast processes within molecules to be observed

08-May-2024 - A European research team has developed a novel spectroscopic method that can be used to observe ultrafast dynamic processes of electrons and vibrations within molecules – with atomic resolution and in real time. A team from the University of Jena supported the experimental team in Barcelona in ...

The world's shortest laser pulse

Observe the movement of electrons during chemical reactions in slow motion

02-Nov-2017 - ETH researchers succeeded in shortening the pulse duration of an X‑ray laser to only 43 attoseconds. With a time resolution in the range of a few quintillionths of a second, they are now able for the first time to observe the movement of electrons during chemical reactions in slow motion. In ...

Record for fastest light pulse set

09-Aug-2017 - A research team at the University of Central Florida has demonstrated the fastest light pulse ever developed, a 53-attosecond X-ray flash. The group led by Professor Zenghu Chang beat its own record set in 2012: a 67-attosecond extreme ultraviolet light pulse that was the fastest at the time. At ...

Scientists measure speedy electrons in silicon

Attosecond laser provides first 'movie' of fast electrons jumping band-gap of semiconductor

22-Dec-2014 - The entire semiconductor industry, not to mention Silicon Valley, is built on the propensity of electrons in silicon to get kicked out of their atomic shells and become free. These mobile electrons are routed and switched though transistors, carrying the digital information that characterizes our ...
