Read moreThe quest to control and understand the intrinsic spin of electrons to advance nanoscale electronics is hampered by how hard it is to measure tiny, fast magnetic devices. Applied physicists offer a solution: using heat, instead of light, to measure magnetic systems at short length and time scales.

Read moreElectron orbitals provide information on the whereabouts of the electrons in atoms and molecules. Scientists have now succeeded in experimentally recording these structures in all three dimensions. They achieved this by further developing a method they had already applied two years ago to make these orbitals visible in two dimensions.

Read moreTo understand how a TMD semiconductor behaves inside a device, researchers investigated the effects of sub-monolayer deposition of alkali atoms at the surface of the semiconductor tungsten selenide. These deposited atoms mimics the electric field effects that a semiconductor would experience inside a transistor, while allowing researchers to directly analyse the electronic structure by a state of the art spectroscopic technique.
