In this work, carbon nanotube samples were produced by aerosol chemical vapour deposition from a solution of ferrocene in benzylamine. The multi-walled nanotubes produced by this method were investigated by TEM, SEM/EDS, scanning tunneling microscopy (STM) and tunneling spectroscopy (STS). The dl/dV curves obtained from the STS measurements showed asymmetric density of states (DOS) in nanotubes, with higher DOS above the Fermi energy. These STS measurements and the EDS analysis indicate successful doping with nitrogen originating from the decomposition of benzylamine.
在本工作中，通过二茂铁在苄胺溶液中的气溶胶化学气相沉积法制备了碳纳米管样品。用透射电子显微镜（TEM）、扫描电子显微镜/能谱仪（SEM/EDS）、扫描隧道显微镜（STM）和隧道谱（STS）对用该方法制备的多壁纳米管进行了研究。从STS测量获得的dl/dV曲线表明纳米管中的态密度（DOS）不对称，费米能以上的DOS较高。这些STS测量和EDS分析表明成功掺杂了源自苄胺分解的氮。
