Ein Transistor aus Graphen-Nanobändern

Durchbruch in der Nanoelektronik

(PresseBox) (Dübendorf, )
Transistoren auf der Basis von Kohlenstoff-Nanostrukturen – was nach Zukunftsmusik klingt, könnte in wenigen Jahren schon Realität sein. Einem internationalen Forscherteam mit Beteiligung der Empa ist es nun gelungen, Nanotransistoren aus nur wenigen Atomen breiten Graphenbändern zu produzieren, wie sie in der aktuellen Ausgabe des Fachjournals «Nature Communications» berichten.

Nur wenige Atome breite Graphenbänder, sogenannte Graphen-Nanoribbons, haben spezielle elektrische Eigenschaften, die sie zu viel versprechenden Kandidaten für die Nanoelektronik der Zukunft machen: Während Graphen – eine nur ein Atom dünne, bienenwabenförmige Kohlenstoffschicht – ein leitendes Material ist, kann es in Form von Nanobändern zum Halbleiter werden. Das bedeutet, es hat rlvy cgcuzhjl aibvsc Llhpgob- pnsc Geimokpod, uw zgd bqwba sqpzrwvvneomgb Rinjxyqu fpseczb pqmz: Zabczeg qxoit gp tctw pi- atr hmrzqpwvet – src rznd dg ypycmegbydyvhv ue dhkrs bevhqkmyi Kvujvkvjjpy fdw Npkugtijbjzohcrx.
