SYHS: Symposium Physics of van der Waals 2D Heterostructures

SYHS 1: Physics of van der Waals 2D Heterostructures

Freitag, 31. März 2023, 09:30–12:15, HSZ 01

Van der Waals heterostructures based on 2D layered materials provide an exciting platform to engineer and control electronic, transport, optical properties, spin, and magnetic properties. Many exciting phenomena have been reported in stacked materials coupled by weak van der Waals interactions. Perhaps most spectacular are strong correlations and superconductivity in graphene and transition-metal dichalcogenides multilayers. Also in the exciton physics, there is a trend towards investigating signatures of many-body effects. New directions of research include searches for novel topological states, investigations of spin and magnetic proximity effects, strain physics, or studying magnetic excitations. The aim of this symposium is to present an overview of some of the recent developments in this field by leading experts in this forefront area of condensed matter physics.
