The field of spintronics deals with ideal devices which can operate using the electron’s spin, rather than its charge. A new class of materials, called topological insulators, is intensively studied in the past years. Their unusual property is that the surface behaves as a metal, whereas its bulk structure has a semiconductor behaviour.
