In our group we aim to control and understand electronic transport at the smallest possible length scale by using individual molecules, atoms or atomic chains as electronic conductors. We take advantage of the structural richness of molecules, the physics of low dimensional materials, and the chemistry of nanoscale interfaces to demonstrate intriguing material properties and novel transport effects that emerge at the atomic scale.

 

For example: we found that quantum interference in single-molecule junctions can generate spin-polarized currents without magnetic components. These findings promote nanoscale spintronic manipulations with the freedom to use nonmagnetic materials (Nature Commun. 2019). In another example: About 100 years after the discovery of shot noise and thermal noise, we identified a fundamental electronic noise contribution that is activated by temperature difference across electronic conductors. This noise, called delta-T noise, can be used to probe temperature differences at the nanoscale, a property that is important for the study of nanoscale energy conversion and power saving processes. Delta-T noise may also be relevant for the modern electronics industry, since temperature differences tend to develop unintentionally across electronic components. Now, careful design can reduce this unknown-to-date noise contribution in nanoscale electronics (Nature 2018).

 

Our research interest includes:

  • Electronic spin-transport and nanoscale magnetism
  • Energy conversion at the atomic and molecular scale
  • Material properties of low-dimensional structures and interfaces
  • Molecular quantum machines
  • Fundamental electronic noise

 

We have open positions for postdoc, PhD and master students in chemistry, chemistry-materiels, and physics tracks.
