New Insights into the Interaction of Topological Insulators

Topological insulators are regarded as the key to novel ‘spintronic’ devices and quantum computers of the future due to their unique electronic properties. Physicists have now been able to understand for the first time how the topological properties of multilayer systems of Tungsten di-telluride can be changed systematically by means of scanning tunneling microscopy. The chemical compound has recently proven to be a promising material for the realization of topological states.
