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

As the spin orientation of photoelectrons can be completely different from their initial states, this work suggests that the photoemission matrix element 7 has to be taken into account in interpreting ...

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 ...

Studies of photoemission processes induced by hard X-rays including production of energetic electrons have become feasible due to recent substantial improvement of instrumentation. Novel dynamical ...

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 ...

Plain-looking but inherently strange crystalline materials called 3D topological insulators (TIs) are all the rage in materials science. Even at room temperature, a single chunk of TI is a good ...
