Talk - Thursday 27th January 11.15-12.00 on Zoom, questions 12.00-12.15 Speaker: Søren Ulstrup, Department of Physics and Astronomy, Aarhus University Title: Visualizing quantum states in atomically thin materials Abstract: There is a striking appeal in the prospect of seamlessly stacking materials with dissimilar properties, like LEGOs with different colors. This approach promises complete freedom to design new components for electronics and optics that not only inherit the qualities of the fundamental building blocks but evolve into something much more unique. The dream of such LEGO-style quantum materials design has come true with the possibilities to isolate and arbitrarily stack atomically thin crystals, so-called two-dimensional (2D) materials. Here, I will briefly outline the evolution of the field of 2D materials since the discovery of graphene and discuss how these materials may realize new forms of electronics such as twistronics. I will show how the quantum states of operating devices based on 2D materials will be directly visualized using synchrotron radiation focused to the nanoscale at a new beamline at ASTRID2. Finally, I will present future opportunities for strategic materials design at the fundamental level of quantum mechanics using this beamline facility.
