Wenn Strom durch gewöhnliche Metalle fließt, herrscht normalerweise ein ziemliches Elektronen-Chaos. Vor wenigen Jahren haben Forscher entdeckt, dass es Materialien gibt, in denen sich die Elektronen mit einer erstaunlichen Ordnung bewegen. Diese ungewöhnlichen Eigenschaften zeigen sie jedoch nur in einer hauchdünnen Schicht an der Oberfläche, ansonsten sind diese toplogische Isolatoren genannte Stoffe elektrisch nicht leitend. Nun hat ein internationales Team von Wissenschaftlern unter Beteiligung von Physikern des Max-Planck-Instituts für Mikrostrukturphysik in Halle eine Methode entwickelt, wie sich topologische Isolatoren mit ganz bestimmten Merkmalen herstellen lassen. Mit solchen Materialien könnten dazu dienen, künftig leistungsfähigere Computer zu konstruieren.
