WIN Seminar: Plasmons and Sensing in Graphene DevicesExport this event to calendar

Tuesday, February 20, 2018 — 3:00 PM to 4:00 PM EST

The Waterloo Institute for Nanotechnology (WIN) is pleased to present a seminar talk by Dr. Mikael Fogelström, from the Department of Microtechnology and Nanoscience, Chalmers University of Technology, Gotebörg, Sweden.

Plasmons and Sensing in Graphene Devices

In this WIN seminar, Dr. Fogelström will discuss the theoretical work his team made on plasmons in graphene, their propagation in different nanostructures and the applications of them. They consider in particular the non-local effects using both a phenomenological hydrodynamic approximation and a fully quantum mechanical microscopic description. They found that non-local effects can be quite substantial, changing the plasmon frequency by up to 20 percent. As an application, his team consider graphene-based plasmonic sensors to detect and identify analytes on the graphene surface as well as other changes in the local electromagnetic environment.

Professor Fogelström’s research focuses on nanoscale superconductivity and quantum transport in 2D materials. It involves the development of efficient numerical studies of charge and energy transport in spatially inhomogeneous systems based on non-equilibrium many body theory.

Dr. Mikael Fogelström holds a PhD in theoretical physics and an MSc in physics from Åbo Akademi, Finland. He is the Department Head of Microtechnology and Nanoscience at Chalmers University of Technology in Gotebörg, Sweden.
