我们通过对设计的微图案线进行电流加热，在预定位置局部合成氧化钨纳米线。电流线由钨薄膜制成，同一根线有两种不同的宽度，由于电阻的差异，较窄的部分比较宽的部分受热更多。较窄部分的温度被控制为最适合在真空室的 O-2 气氛中合成纳米线。我们在大约 1 x 1 μ m(2) 的区域上演示了纳米线的合成，并成功地在规则的 20 x 20 阵列上合成了具有 10 μm 节距的狭窄部分的纳米线。 (C) 2008 日本应用物理学会。
We locally synthesized tungsten oxide nanowires at predetermined positions by current heating of designed micropatterned wires. The current wires were fabricated from tungsten thin film and had two different widths in the same wire, and the narrower sections were heated more than the wider sections due to the difference in electric resistance. The temperature of the narrower sections was controlled to be optimal for nanowire synthesis in an O-2 atmosphere in a vacuum chamber. We demonstrated the synthesis of nanowires over an area of approximately 1 x 1 mu m(2) and successfully synthesized nanowires on a regular 20 by 20 array with narrow sections with 10 mu m pitch.
