Manipulating the topological properties of thin heterostructures
Centre of Low Temperature Physics, Institute of Experimental Physics, Slovak Academy of Sciences, Košice SK-04001, Slovakia
Topological materials host robust properties, unaffected by microscopic perturbations, owing to the global geometric properties of the bulk electron system. Materials in which the topological invariant can be changed by easily tuning external parameters are especially sought after. In my presentation I will introduce different two-dimensional heterostructures that change their topological flavour under modest mechanical strain.
