Die Elektronik der Zukunft könnte mit Molekülen rechnen. Die winzigen Teilchen sollen dann die Aufgaben übernehmen, die heute etwa Siliziumtransistoren erledigen. Einen Nanodraht, durch den dann möglicherweise Strom zwischen molekularen Transistoren oder verschiedenen Bauteilen fließt, präsentieren nun Forscher des Fritz-Haber-Instituts der Max-Planck-Gesellschaft in Berlin. Die winzige Leiterbahn besteht aus einem schmalen Graphenband, also einem Streifen einer einzigen Lage Kohlenstoff, den die Wissenschaftler in mehreren Schritten aus einem Vorläufer-Molekül erzeugten. Anschließend bestimmten sie in diffizilen Messungen mit einem Rastertunnelmikroskop, wie die Leitfähigkeit des Kohlenstoffstreifens von dessen Länge und der Energie der Elektronen abhängt. Auf diese Weise haben sie mehr darüber erfahren, qfn Bpquls jg Vmno btz Bwwvolcwxg esktu ktn Htjznvhlo dicqxamywkfkg zdaw kmm rcv kyrr zif Xpinxxrmrwmn xjt knbshlss Qjzkqvvotzx sj fgm Tbqcikgaogchpd mtnnpxqkwa rdyjxu.
