Atom für Atom zu neuen Materialien

Überblick

Woraus besteht das Handy von übermorgen? Forscher:innen des Dresden-Würzburger Exzellenzclusters ct.qmat dringen zu den Eigenschaften neuer Quantenmaterialien vor, die unter extremen Bedingungen wie ultratiefen Temperaturen, hohem Druck oder starken Magnetfeldern überraschende Phänomene aufweisen. Wenn es gelingt, diese Eigenschaften unter Alltagsbedingungen nutzbar zu machen, könnten Quantenmaterialien zum Beispiel Handy-Bauteile ermöglichen, die den Energieverbrauch drastisch senken, die Speicherkapazität deutlich erhöhen und ungeahnte Funktionen gestatten.
 

Unter dem Titel „Wie werden wir in Zukunft leben?“ präsentiert DRESDEN-concept aktuelle kooperative Forschungsprojekte und Innovationen in den Forschungsfeldern Digitalisierung, Leben, Klima & Wasser, Mobilität, Material und Kulturgut. Drei Gucklöcher und ein QR-Code laden zum Entdecken und Verstehen des Exzellenzclusters ct.qmat ein.
 
Ein revolutionäres Material made in Dresden heißt Mangan-Bismut-Tellurid – kurz MnBi2Te4. Juniorprofessorin Dr. Anna Isaeva berichtet in einem YouTube-Video, auf welch detektivische Weise sie und ihr Team nach den Herstellungsbedingungen des neuen Quantenmaterials fahndeten – und welche spannenden Möglichkeiten es für die Zukunft verspricht. Das Atom für Atom designte Kristall ist ein magnetischer topologischer Isolator: Verlustfrei leitet dieses Material auf seiner Oberfläche Strom, während es innen isoliert. Dabei braucht es kein starkes äußeres Magnetfeld: MnBi2Te4 bringt sein Magnetfeld selber mit.
