The creation of photoelectrons through ionization is one of the most fundamental processes in the interaction between light and matter. Yet, deep questions remain about just how photons transfer their ...

For the first time, researchers have been able to measure the quantum state of electrons ejected from atoms that have absorbed high-energy light pulses. This is thanks to a new measurement technique ...

High efficiency: artist’s impression of electrons emitted from the surface of a photocathode. (Courtesy: Shutterstock/Anteromite) An ultrathin photocathode that is ...

Electrons flowing swiftly across the surface of topological insulators (TIs) are "spin polarized," their spin and momentum locked. The potential to control electron distribution in spintronic devices ...

IT is well known that the emission of photoelectrons by X-rays is not symmetrically distributed about the plane normal to the rays, the photoelectrons possessing an average momentum in the ‘forward’ ...
