| 中文摘要 | Vertically aligned single-crystal SnO2 nanoshuttle arrays with uniform morphology and a relatively high aspect ratio were synthesized by a simple hot-wall chemical vapor deposition (CVD) method. It was found that regulating the growth temperature gradient could change the shape of the SnO2 nanostructure from nanoshuttles to nanochisels and nanoneedles, and a self-catalyzing growth process was responsible for tunable morphologies of SnO2 nanostructures. The as-synthesized SnO2 nanoshuttles showed ultrahigh flexibility and strong toughness with a large elastic strain of similar to 6.2, which is much higher than reported for Si and ZnO nanowire as well as most crystalline metallic materials. The field emitter fabricated using SnO2 nanoshuttle arrays has a low turn-on electric field of around 0.6 V mu m(-1), and a high field emission current density of above 10 mA cm(-2), which is comparable with the highest emission current density of carbon nanotube and nanowire field emitters. |
