Watching the hidden life of materials - Ultrafast electron diffraction experiments open a new window on the microscopic world

Researchers at McGill University have succeeded in simultaneously observing the reorganizations of atomic positions and electron distribution during the transformation of the "smart material" vanadium dioxide (VO2) from a semiconductor into a metal - in a time frame a trillion times faster than the blink of an eye.
