摘要：

In this work, CNTs have been bombarded with low energy N ions. X-ray photoelectron spectroscopy have been used to determine the binding configuration of the N-doped CNTs. AFM was also used to determine their morphology and mechanical properties. The same morphology is maintained after the N-2(+) bombardment. XPS analysis shows that the N Is core level spectra for N-doped CNTs can be deconvoluted in terms of two peaks related to sp(2) (C-N=C) and sp(3) hybridization (C-N configuration). This interpretation is in concordance with the increase of the hardness observed by AFM nanoindentations when the sp(3) contributions increase. (c) 2006 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
