Ultrashort laser pulses let new microscope map electron interactions across thin materials
A new type of advanced microscope (wide-field coherent multidimensional microscopy) has been developed.
A new type of advanced microscope (wide-field coherent multidimensional microscopy) has been developed.
The short version
- It uses a carefully designed sequence of ultrashort light pulses to study the behavior of high-tech materials, with potential practical applications in the study of innovative materials such as those used to build solar panels.
- This article has been reviewed according to Science X's editorial process and policies .
- The new microscope can track phenomena that occur over incredibly short time frames, on the order of a few millionths of a billionth of a second.
What happened
To achieve this, the microscope uses extremely short laser light pulses and observes the material's reaction step by step to understand the mechanisms of electron interaction in different regions of a microelectronic device. This type of microscope was developed for the first time at the ILAMP laboratories in Brescia, in collaboration with Politecnico di Milano, KU Leuven, the University of British Columbia and the CNR.
Why it matters
It works by creating a sequence of identical light pulses that illuminate a sample placed inside the microscope.
