Department of Applied Physics

Atomic Scale Physics

We focus on the experimental study of atomically well-defined nanostructures, where the precise nature and location of every atom matters. We use low-temperature scanning probe microscopy that allows structural and electronic characterization, and manipulation of materials down to the atomic scale.

Current focus:

  • Artificial designer materials using 2D van der Waals materials, molecular self-assembly, and heterostructures
  • Atomic scale characterization and modification of materials based on scanning probe techniques
  • Chemistry and physics of single molecules
