摘要

The electronic structure of individual carbon nanotubes (CNTs) with different diameters has been investigated by scanning transmission X-ray microscopy (STXM). Various factors that may alter the STXM spectral features in CNT bundles have been discussed. Tube diameter has been found to be proportional to the spectral intensity, whereas it has negligible effect on the spectral shape. Disordered structure in CNTs introduced in the synthesis process was observed, which significantly affected the X-ray absorption spectrum by a reduction of the π* excitation. Moreover, tube—tube interaction in CNT bundles was detected, which can enhance the π* excitation. Insights into the nature of CNT bundles with various electronic structures may provide a new vision to understand the performance of CNT-based devices.
