The ability to manipulate the spin orientation of the highly spin-polarized photoelectrons ejected from topologically protected surface electrons by light polarization may pave the way for ...

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 ...

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 ...

Physicists had already tried to measure the quantum state of photoelectrons using a different method, and those experiments showed that it is very difficult. Everything has to be very stable over a ...

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 ...

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 ...
