| New group picture 2020-06-30  Working on site is more and more possible in the department. Still we do our weekly group meetings via video conference. | ||
| New article published in Communications Materials 2020-02-28  New results published in Communications Materials. Using atomic force microscopy at Room and Low temperature combined with molecular dynamics, we studied the thermal expansion coefficient of 2D molecular islands based on spoked wheel molecules. We find that the increasing motion, with temperature, of the alkyl chains is responsible of the giant thermal expansion coefficient we measured. | ||

| New article published in Nature Materials 2019-10-24  Our results on a new quantum-mechanical dissipation mechanism that occurs only at certain voltages on topological insulator surface is published in Nature Materials. At the specific tip-sample voltage and distance, the single electron migrate from the tip through an intermediate image potential state into the material. The mere presence of a single charge carrier in electronic state strongly influences the energy dissipation on topological insulator surface. | ||

| nc-AFM Award for Prof. Alexis Baratoff 2019-08-12  During the 22nd international ncAFM conference (July 29th to August 2nd, 2019) in Regensburg, Prof. Alexis Baratoff got the nc-AFM award for his theoretical contributions in this field of research. The award is a 40 million times enlarged model of the Silicon 7x7 surface. Original data were obtained by the non-contact AFM with a CO-terminated tip by Emmerich et al [Science 348, 308 (2015)] and then machined by the workshop of the University of Regensburg.
