Carbon Nanotubes on Highly Orientated Pyrolytic Graphite
躺在石墨表面上的碳纳米管

Carbon nanotubes on highly orientated pyrolytic graphite ( HOPG ) were studied with a scanning tunneling microscope ( STM ) operated at room temperature in ambient conditions. The atomic structure, I\|Vproperties and the surface profiles of aggregation are carried out. The surface profiles correspond with the images through transmission electron microscopy ( TEM ). Aggregating nanotubes are immersed in ethanol and ultrasonically agitated to separate the individual tubes because of the weaker hydrophobic proximity effect between the nanotubes.
