Erfolgreiche Phosphor-Dotierung von ZnO-Nanodrähten

(PresseBox) (Leipzig, )
Der Arbeitsgruppe Halbleiterphysik der Universität Leipzig ist es jetzt gelungen, Phosphor-Atome stabil in ZnO:P Nanodrähte einzubauen (Phosphor-Dotierung). Damit gelang den Wissenschaftlern die Herstellung von hochwertigen, spannungs- und defektarmen ZnO-Nanodrähten, die besonders für blau und ultraviolett leuchtende LEDs und Laserdioden geeignet sind.

Eine wesentliche Voraussetzung für photonische Anwendungen des oxidischen II-VI-Halbleiters Zinkoxid (ZnO) ist der Nachweis einer zeitlich stabilen sogenannten p-Typ Leitfähigkeit im ZnO. Diese auch als Löcherleitung bezeichnete Leitfähigkeit stellt weltweit eine große Herausforderung dar, und die Fortschritte bei dieser anspruchsvollen Thematik waren bisher eher spärlich. "Wir konnten nun einen herausragenden Fortschritt bei der Phosphor-Dotierung von ZnO-Nanostrukturen (ZnO:P) erzielen", sagt Qamikbyks Nf.
