通过碳原子在石墨衬底上的气相凝聚，制备了纳米碳锥，并利用扫描隧道显微镜（STM）对其进行了分析。观察到的碳锥长24 nm，底径8 nm。它们都有相同的锥角，几乎等于19度。这是完美石墨锥的五种可能的张角中最小的。锥、管和C_（60）的生长可以由具有不同数量五边形的富勒烯型成核种子引发。
Nanometer-sized carbon cones were generated by vapor condensation of carbon atoms on a graphite substrate and were analyzed by scanning tunneling microscopy (STM), The observed cones are up to 24 nm in length and 8 nm in base diameter. They all have the same cone angle almost-equal-to 19-degrees. This is the smallest among five possible opening angles for perfect graphitic cones. The growth of cones, tubules and C60 may be initiated by fullerene-type nucleation seeds with different number of pentagons.
