Race of the electrons: Laser pulses can be used to track the motion of electrons in metals with attosecond precision

14 enero 2015

Light can rip electrons out of a piece of metal. This ‘photoelectric effect’ is extremely fast. But now modern attosecond technology can resolve the time evolution of such processes. A new article discusses the race of electrons in a layered structure made of magnesium and tungsten.
