Electron Spectroscopy

The banner image shows a section of the phonon dispersion of graphene measured with the MCES150 that was developed in our institute and is commercially available from ScientaOmicron.

About

We develop high-intensity and high-resolution electron sources to study collective charge modes in model materials that are relevant for topological quantum computing. We also establish new approaches for the epitaxial growth of 2D materials.

Research Topics

  • Monochromatised electron source
  • Graphene
  • Chemically-resolved vertical structures with sub-Angstrom resolution
