Graphical Abstract
Vielversprechende Bausteine: Radial ausgerichtete amorphe Silica-Nanodrähte wurden in hoher Dichte auf einem einkristallinen Si-Nanokern durch einfache thermische Verdampfung von Silicium in Gegenwart von Zinn als Katalysator synthetisiert. Wahrscheinlich umfasst der Wachstumsprozess (siehe Schema) sowohl Dampf-flüssig-fest(VLS)- als auch Oxid-unterstützte (OA) Mechanismen. Gezeigt sind Rasterelektronenaufnahmen der Spezies 1 und 2.
