We have performed a detailed investigation of the basic electronic transport properties of single walled carbon nanotubes (SWCNT) organized in macroscopic ribbons (some millimeters long with a transversal size of tens of microns), and formed predominantly by identical nanotubes. High resolution TEM and Electron diffraction techniques have been applied in order to determine the peculiar aggregation of SWCNTs in homotype bundles. The electronic properties of individual SWCNT bundles have been investigated by scanning tunneling microscopy and spectroscopy (STM/STS). The electrical features of the ribbons have been investigated in the 100–500 K temperature range using a multifinger device. Overall, the results indicate the possibility to control the local density of state energy by tailoring different architectures
