- Topological matter: Topological insulators, Dirac semimetals, Weyl fermions, and more, visualising both protected band crossings and surface states.
- High‑Tc and heavy fermion superconductors: Studying superconducting gaps, related phase transitions, ultra-small bandwidth dispersions
Applications of ARPES
Technique
- Transition metal oxides: Quantitative analysis of electron interactions, Fermi surfaces, renormalisation, energy gaps.
- Transition metal dichalcogenides and other quasi‑2D materials: Electronic and magnetic phase transitions, band structure determination, surface dosing studies.
- Carbon‑based materials: Graphene, including bilayers, nanoribbons,, rhombohedral stacking, and twisted bilayer graphene.
- In situ operando studies of micro‑devices: available using the nanoARPES setup.
- Surfaces & Interfaces: Molecular adsorbates, ultrathin films, stepped surfaces, epitaxially grown nano‑wires, topological insulators.
