Angle-Resolved-Photoelectron-Spectroscopy (ARPES) is an experimental technique to measure the electronic structure of solids, allowing also detailed insights into complex electron – electron and electron – lattice interactions. ARPES measurements are extremely important since all properties of materials (mechanical, thermal, optical, magnetic, and whatever else one can imagine) are programmed with the material electronic structure.
This video showcases how ARPES work, the kind of samples that can be studied with it, and the research domains it can be used for.
