摘要
报道了一种用60keVAr+轰击石墨生成碳纳米管和纳米碳壳层多面体颗粒的方法.高分辨透射电子显微镜研究指出,这些纳米多层结构物的尺寸约在20nm到04μm之间,碳原子层之间的距离为034nm.基于高分辨透射电子显微镜图像,建议了一个关于“组合碳多面体”的生长模型.
Abstract ? We report a method of carbon nanotube and nano polyhedron growth in graphite surface by 60keV Ar + ion beam bombardment. High resolution transmission electron microscopy (HRTEM) reveals that the nanostructures range from ~20nm to ~0 4μm in size and the distance between carbon layers in multilayer walls is 0 34nm. Based on HRTEM images, we propose a growth model of “combined carbon polyhedron”.
