Keywords: carbon nanotubes; CNT growth; metal clusters; size selected clusters; Introduction Controlling the individual diameters of carbon nanotubes (CNTs) is still one of the major challenges in current CNT research, and it is particularly important as it determines
  • crystal [6]. Size-defined, sub-nm, ligand-free metal clusters would be an interesting synthetic alternative to obtain CNTs with controlled diameter. However, such small metal clusters can only be generated by gas-phase techniques, typically in a ligand-free environment as naked clusters. A controlled
  • study of 3-D metal clusters as catalysts in CNT growth was reported in [8], however, no CNT growth was studied therein; CNT growth derived from nm-sized, ligand-stabilized mixed metal clusters as precatalysts was reported in [9].) Non-agglomerated naked iron clusters of 0.6–0.9 nm size were generated

For instance, nitric oxide decomposition on thin film aluminum oxide preferentially takes place at the APDBs [52]. It has been predicted by means of DFT calculations [47] that

A major issue is that nanoparticles are usually moved individually so that the AFM tip has to be properly positioned with
