Comparison of the electronic properties of sorted metallic and semiconducting nickelocene-filled single-walled carbon nanotubes

In present work, we investigated single-walled carbon nanotubes (SWCNTs) filled with nickelocene utilizing the gas phase method. We investigated the electronic properties of sorted metallic and semiconducting nickelocene-filled SWCNTs using angle-resolved photoemission spectroscopy. This allowed obs...

Description
Summary:In present work, we investigated single-walled carbon nanotubes (SWCNTs) filled with nickelocene utilizing the gas phase method. We investigated the electronic properties of sorted metallic and semiconducting nickelocene-filled SWCNTs using angle-resolved photoemission spectroscopy. This allowed observing the variation of the Fermi level between different measurement angles, which is connected with the modification of the electronic properties of the nanotubes. The Fermi level varied significantly between nanotubes with different metallicity. This is explained by different effectivity of charge transfer in different samples due to different conductivity type, length of nickel clusters and homogeneity of filling of SWCNTs.
