Applications

The HR branch of I05-ARPES has a wide range of applications that include:

Topological matter
Topological insulators, Dirac semimetals and investigation of the Weyl fermions.

Transition metal oxides
Quantitative analysis of electron interactions, Fermi surfaces, renormalisation, energy gaps;

High-Tc superconductors and Heavy Fermions
Superconducting gaps, related phase transitions, Ultra small bandwidth dispersions;

New materials
ARPES as soon as single crystals are grown, nano-ARPES from inclusions and samples that are difficult to cleave;

Surfaces & interfaces
Molecular adsorbates, ultrathin films, stepped surfaces, epitaxially grown nano-wires, topological insulators.

Transition metal dichalcogenides and other quasi-2D materials
Electronic and magnetic phase transitions, band structure determination, surface dosing studies

The nano-ARPES branch can be used to study some aspects of the above, and is additionally suitable for:

Micro-devices
The nanoARPES option to have 4 or 5 electrical connections to sample provides opportunity for in-operando studies of micro-devices

Carbon-based materials
Graphene, molecular electronics, carbon nanotubes, BN nanostructure; bilayers and twisted bilayer graphene.
