В четверг 5 июня в 15:00 состоится семинар лаборатории Laboratoire de Physique et d'Étude des Matériaux (LPEM), École Supérieure de Physique et de Chimie Industrielles (ESPCI Paris).
С докладом на тему "Hybrid plasmons in TI heterostructures" выступит Timothy Moorsom University of Leeds, UK.
Аннотация: Topological Insulators have fascinated condensed matter physics for over 15 years thanks to the properties that emerge in their protected surface states. Potential applications include efficient spin-charge conversion, 2D superconductivity and, of course, the much sought after Majorana Zero Modes. However, TIs also have applications in photonics as broad-band photo-detectors, plasmonic meta-materials and converters. Engineering heterostructures from TIs with ideal properties requires a deep understanding of surface and interfaces effects in these materials. These insights can be gained by employing advanced electron-microscopy to investigate both structure and excitations in complex TI multilayers. I will showcase recent work undertaken at the Leeds Electron Microscopy And Spectroscopy facility, as well as the SuperSTEM national microscopy centre in the UK, to map hybrid plasmons and excitations in these materials down to the atomic scale and demonstrate the new hybrid structures we are now exploring using the multi-functional Royce Deposition System.
