The Faculty of Physics at the University of Warsaw would like to invite to a lecture by Prof. Marcin Konczykowski entitled “Irradiation-controlled point disorder: test of models and path to novel electronic states.”
Professor Marcin Konczykowski is a renowned specialist in condensed matter physics, working at the Laboratory of Irradiated Solids (Laboratoire des Solides Irradiés) at École Polytechnique in Palaiseau near Paris. He specializes in disorder effects in condensed matter, superconductivity, vortex dynamics, and irradiation effects. He is the author of over 330 scientific articles, which have been cited over 9,000 times in total.
A common feature of crystalline materials is their sensitivity to disorder, from semiconductor doping to the plasticity of metals controlled by dislocation motion. The presence of even a small number of defects plays a key role in shaping the properties of materials. On the other hand, traces of crystallinity determine the properties of amorphous matter. Since the concentration of native defects is established during sample growth under repeatable conditions, it is often considered an intrinsic property. This overlooks the fact that at sufficiently low temperatures, crystalline material is in a metastable state determined by the migration energy of native defects. In his presentation, Prof. Konczykowski will illustrate these statements with experiments based on the controlled modification of point defect concentrations using high-energy particle irradiation.
The event, organised as part of Action I.1.1/IV.1.1 “Mentoring Programme”, will take place on 28 November 2025 at 10:15 a.m. at the Faculty of Physics, University of Warsaw, ul. Pasteura 5 (room 0.06).
