Pyrolysis of 2-amino-4,6-dichloro-s-triazine over laser-etched thin films of cobalt deposited on an inverted silica substrate generates aligned bundles and films of carbon nanotubes of uniform dimensions. Scanning electron microscopy, high resolution transmission electron microscopy, energy dispersive X-ray analyses, electron energy loss spectroscopy and electron diffraction studies reveal that the aligned tubes, which usually grow perpendicular to the substrate surface, are mainly straight (length ⩽100 μm; 30–50 nm OD), contain traces of nitrogen (

激光刻蚀钴薄膜催化制备取向碳纳米管

2-氨基-4,6-二氯-s-三嗪在沉积在倒置二氧化硅基板上的激光蚀刻钴薄膜上的热解产生了排列均匀的束和均匀尺寸的碳纳米管薄膜。扫描电子显微镜，高分辨率透射电子显微镜，能量色散X射线分析，电子能量损失谱和电子衍射研究表明，通常垂直于基板表面生长的对准管主要是直的（长度⩽100μm； 30） –50 nm OD），含有微量氮（
