ResumoVertically aligned bundles of molybdenum–sulfur–iodine nanowires (MoSIx) were grown on a molybdenum foil, thin wire, and quartz substrate. By choosing different growth parameters we have been able to vary the surface density from ∼0.01 to 0.5 bundless/μm2 and the length of the nanowire bundles from ∼30 μm to 15 mm. In the case of growth on molybdenum, resistivity measurements show that a good electrical contact exists between the bundles and the metal substrate. The nanowires are found to have excellent field emission properties, competitive with state-of-the-art carbon nanotube large-area field emitters.
