WO3 nanorods targeted for applications in electric devices were grown from a tungsten wire heated in an oxygen atmosphere inside an environmental transmission electron microscope, which allowed the growth process to be observed to reveal the growth mechanism of the WO3 nanorods. The initial growth of the nanorods did not consist of tungsten oxide but rather crystal tungsten. The formed crystal tungsten nanorods were then oxidized, resulting in the formation of the tungsten oxide nanorods. Furthermore, it is expected that the nanorods grew through cracks in the natural surface oxide layer on the tungsten wire.
用于电子器件应用的三氧化钨纳米棒是在环境透射电子显微镜内的氧气气氛中加热钨丝生长而成的,这使得能够观察生长过程以揭示三氧化钨纳米棒的生长机制。纳米棒的初始生长并非由氧化钨组成,而是由晶体钨组成。然后,形成的晶体钨纳米棒被氧化,从而形成氧化钨纳米棒。此外,预计纳米棒是通过钨丝天然表面氧化层中的裂缝生长的。
