HIGH YIELD SYNTHESIS OF CARBON NANOTUBE ARRAYS BY PYROLYSIS OF BENZENE/METALLOCENE AEROSOLS

High Resolution Transmission Electron Microscopy (HRTEM) studies reveal that these tapering structures are fully filled with Ni and are closed at both ends.

The TEP of boron doped nanotubes is positive, indicating hole-like carriers. In contrast, the nitrogen doped material exhibits negative TEP over the same temperature range, suggesting electron-like conduction. Therefore, the TEP distinct nonlinearites are primarily due to the formation of donor and acceptor states in the B-and N-doped materials. The sharply varying density of states used in our model can be directly correlated to the scanning tunneling spectroscopy studies of these materials.

Raman Study of Doped Multiwalled Carbon Nanotubes

Nitrogen doped multiwalled nanotubes (N-MWNTs) and boron doped multiwalled nanotubes (B-MWNTs) ha... more Nitrogen doped multiwalled nanotubes (N-MWNTs) and boron doped multiwalled nanotubes (B-MWNTs) have been prepared by chemical vapor deposition and arc-discharge method, respectively, and acceptor and donor states have been verified by Scanning Tunneling Spectroscopy. These doped materials have been studied by Raman Scattering and compared to un-doped multiwalled nanotubes (MWNTs). It is theoretically predicted that B-MWNTs all share the same chirality so particular attention is paid to these materials. Due to the growth method and the ``bamboo'' structure of the N-MWNTs difficulties arise in the interpretation of the Raman modes. FTIR and Absorption measurements have also been made.
