Abstract: Carbon nanotubes containing nitrogen encapsulated in nanocontainers regularly distributed along the tube axis, have been produced by pyrolysing camphor in the presence of a mixture of nitrogen and ammonia gas. Spatially resolved electron energy-loss spectroscopy (EELS) analysis reveals that N2 molecules are contained within the nanocapsules. The well-graphitized walls can be punctured by electron irradiation, thus partially releasing N2. This process is accompanied by the formation of amorphous CNx islands, as demonstrated by dynamic recording and analysis of time- resolved EELS sequences. Such local in situ electron beam nanomachining and nanoanalysis provide a method for producing under control new classes of nanodevices.
