Joost Ridderbos is leaving us. He will go back to the University of Twente and work in the group of Floris Zwanenburg where he did his PhD. However, we will continue to collaborate in various project including the FET-open project TOPSQUAD
Today, our paper on strained induced scalar potential in graphene appeared, see: publication. When graphene is uniaxially strained, the unit cell is elongated which leads to a chnage in the binding energy. This change has the same effect as an electrostatic
Mehdi Ramezani’s paper entitled Superconducting Contacts to a Monolayer Semiconductor just appeared today (24th of June 2021) in Nano Letters. See: link-to-paper Schottky barriers in semiconductors usually prohibit achieving transparent enough contacts required to induce superconductivity in the semiconductor by the
We have recorded a video for the dissemnination of the TOPSQUAD project. See here:
We offer a joint PhD fellowship for a young, highly motivated student for reserach in twisted bilayers in the groups of Prof. Mitali Banerjee (EPFL-Lausanne) and Christian Schönenberger (University of Basel), Switzerland. –> More
Graphene, the first truly two-dimensional material isolated, is never perfectly flat. Even when it is sandwiched between other atomically flat crystals, it still slightly ripples. These out-of-plane corrugations, the deformation of the graphene layer into the third dimension, have profound
David successfully defendes his Phd on the 15th of October, Congratulations! His commitee consited of Dr. Sophie Guéron (Univ. Paris Sud, Orsay) and Prof. Dr. Stijit Goswami (TU-Delft). Thanks a lot to them for their careful reading of the manuscript!
There are various ways to measure the magnetic field, for example, by the force exerted on a ferromagnetic needle, by the voltage measured at the two ends of a wire wound into a coil or through the Hall effect that
we are just back from a great (but quite tough … at least for the boss) hike that started in a village called Curaglia closed to Disentis. We walked up to the Medelserhütte , which is a small but very nice
