I05 beamline is dedicated to Angle-Resolved Photoemission Spectroscopy (ARPES) at Diamond - a technique used to study the electronic structure of materials. It maps the dispersion of electronic bands near the Fermi level and the Fermi surface by exciting electrons in a sample with a specific photon energy. The method conserves the momentum parallel to the surface, making it ideal for studying layered, low-dimensional materials. Additionally, ARPES can analyse the three-dimensional momentum distribution in metallic single crystals, provided the surface is clean and prepared in ultra-high vacuum conditions.
Benefits:
- Provides the most direct probe of the electronic band dispersion in crystalline solids
- It offers very high energy/momentum resolution and count rate.
Best For:
- Carbon based materials: graphene, carbon nanotubes and BN nanostructures
- Transition metal oxides
- Heavy Fermions
- Thin films, nanowires and topological insulators.
