Ein scharfer Blick fürs Unsichtbare

Infrarot-Detektoren aus Quantenpunkten

(PresseBox) (Dübendorf, )
Von smarten Textilien bis hin zu selbstfahrenden Autos: Empa-Forschende entwickeln neuartige Detektoren für Infrarot-Strahlung, die nachhaltiger, flexibler und kostengünstiger sind als bisherige Technologien. Der Schlüssel dazu ist nicht (nur) die Zusammensetzung des Materials, sondern auch seine Grösse.

Was haben Bewegungsmelder, selbstfahrende Autos, chemische Analysegeräte und Satelliten gemeinsam? Sie alle enthalten Detektoren für Infrarot-Strahlung. Diese Detektoren bestehen meistens aus einem kristallinen Halbleitermaterial – dem eigentlichen Detektor, zum Beispiel aus Silicium – und Elektronik zum Auslesen der Daten. Solche Halbleitermaterialien sind oft aufwändig in der Herstellung, die bei sehr hohen Temperaturen stattfinden muss und viel Energie verbraucht. Empa-Forschende sind überzeugt: Das geht
