Ultrafast Dynamics in Nanoscale Systems Group

Group Leader: Klaas-Jan Tielrooij

Main Research Lines

  • Heat and charge transport in systems based on 2D materials

  • Ultrafast optoelectronic techniques

  • Photodetection and terahertz technologies

  • Nanofabrication of systems based on 2D materials

The main goal of the ICN2 Ultrafast Dynamics in Nanoscale Systems Group is to probe, understand and exploit ultrafast phenomena that take place at the nanoscale. These phenomena are characterized by very rich physics with far-reaching implications in terms of material and system properties, as well as technological applications in fields such as thermal management, thermoelectrics, photodetection and quantum technologies.

Currently, the main systems under investigation are based on two-dimensional, layered materials, and hybrid Van der Waals heterostructures. In particular, the group studies the exciting interplay between different carriers of heat: photons, electrons and phonons in these systems. This research takes place within the framework of the ERC Starting Grant project CUHL – Controlling Ultrafast Heat in Layered materials. The group also leads the BIST Ignite project 2DNanoHeat, studying heat transport in topological insulators.

Dr Klaas-Jan Tielrooij

Klaas-Jan Tielrooij joined the ICN2 in October 2018, starting the ICN2 Ultrafast Dynamics in Nanoscale Systems Group. In July 2018, he was awarded a visiting professorship at the Graduate School of Excellence “Material Science in Mainz” (Germany). Before coming to the ICN2, he was a research fellow at fellow-BIST institute ICFO in Barcelona. He obtained his Ph.D. at the University of Amsterdam (Netherlands) in December 2010. He was awarded an ERC Starting Grant in 2018.
