Monoclinic gallium oxide nanowires are prepared here by are discharge of Ga
N powder in the presence of a small amount of transition metal catalyst. Th
e nanowires are characterized by X-ray diffraction, energy dispersive X-ray
spectroscopy, and Raman spectroscopy, and evidence as to the mechanism of
their formation (shown in the Figure) is obtained by high-resolution transm
ission electron microscopy.
