The photoemission or photoelectric effect is a quantum electronic phenomenon in which electrons (photoelectrons) are emitted from matter after the absorption of energy from electromagnetic radiation ...

According to a study published in ACS Nano, a Spanish-German team discovered that inserting a few monolayers of the ...

Spintronics uses the spins of electrons to perform logic operations or store information. Ideally, spintronic devices could ...

"Angle-resolved photoemission spectroscopy is a powerful experimental technique for physicists to understand how electrons ...

For his monumental work in transforming our understanding of gravity and spacetime, Albert Einstein won his sole Nobel Prize for something else: explaining the photoelectric effect. In the early ...

Spintronic devices work with spin textures caused by quantum-physical interactions. Scientists have now studied graphene-cobalt-iridium heterostructures at BESSY II. The results show how two desired ...

Researchers have directly observed Floquet states in semiconductors using all-optical spectroscopy under ambient conditions, ...

Spintronics uses the spins of electrons to perform logic operations or store information. Ideally, spintronic devices could operate faster and more ...

Two-dimensional materials are substances with a thickness of a few nanometres or less. Electrons in these materials are free to move in the two-dimensional plane, but their restricted motion in ...
