Growth mechanism of SnO2 nanomaterials derived from backscattered electron image and EDX observations

SnO2 nanomaterials were synthesized using the unseeded, non-catalytic horizontal vapor phase growth (HVPG) deposition. The sample was synthesized at a growth temperature of 1200oC and growth time of 6 hours. The resulting nanostructures ranges from nano- wires, nanorods to nanobelts as confirmed by...
