Topological insulators are innovative materials that conduct electricity on the surface, but act as insulators on the inside. Physicists at the University of Basel and the Istanbul Technical University have begun investigating how they react to friction. Their experiment shows that the heat generated through friction is significantly lower than in conventional materials. This is due to a new quantum mechanism, the researchers report in the scientific journal Nature Materials.

Thanks to their unique electrical properties, promise many innovations in the electronics and computer industries, as well as in the development of quantum computers. The thin surface layer can almost without resistance, resulting in less than traditional materials. This makes them of particular interest for .
