Abstract

Germanium dioxide (GeO) whiskers were synthesized via pulsed KrF excimer laser ablation at 820 °C in an argon atmosphere. Analysis by energy dispersive X-ray spectroscopy mounted on the SEM revealed germanium and oxygen content while TEM micrographs showed uniform crystal diameters from root to tip. Selected-area electron diffraction pattern further revealed hexagonal single crystals. Investigations support that whisker growth followed vapor-solid transfer mechanism. These properties show great promise for use as whisker/nanorod substrate materials for semi- or superconductor thin film devices.
