Abstract

original image

Reine Kristalle: Durch Ionenaustausch an Halbleiterkristallen wurden Materialien mit unbefriedigenden optoelektronischen Eigenschaften wie einer geringen Photolumineszenz-Quantenausbeute erhalten. Der Grund für die geringe Quantenausbeute dieser Kristalle sind Unreinheiten. Nanostrukturen, die durch Kationenaustausch erhalten wurden, konnten nach dem Austausch gereinigt werden und lieferten qualitativ hochwertige Kristalle (siehe Bild).
