What is Angle-Resolved Photoemission Spectroscopy (ARPES)? Angle-resolved photoemission spectroscopy (ARPES) is a powerful experimental technique used to study the electronic structure of materials.

Excitons, a bound state of an electron and an electron hole, can form when a given material absorbs a photon above its bandgap energy. The photon excites an electron from the valence band into the ...

The emergent phenomena that characterize quantum materials have received prominent exposure thanks to experimental techniques based on photoemission. In turn, the challenges and opportunities ...

The rapid development of two-dimensional quantum materials, such as twisted bilayer graphene, monolayer copper superconductors, and quantum spin Hall materials, has demonstrated both important ...

Electron movement and structures described in quantum physics allow researchers to better understand how and why materials like superconductors behave as they do. Rice University researchers Jianwei ...

One of the big themes of the talks I went to at last week's March Meeting was the exploration of exotic materials, with names like "topological insulators" and "Weyl semi-metals." While there are a ...

Research in quantum materials is paving the way for groundbreaking discoveries and is poised to drive technological advancements that will redefine the landscapes of industries like mining, energy, ...

(Nanowerk News) Using the Advanced Light Source (ALS), researchers determined that interactions between electrons are what give rise to the divergent effects observed when graphene is doped with ...
