Dual-iteration density gradient ultracentrifugation isolates nearly single diameters of monodisperse metallic arc discharge SWCNTs. Subsequently fabricated conductive thin films possess distinct colors due to well-defined transmittance windows flanked by sharp optical transitions. Measurements of uniform sheet resistances and work functions confirm the largely invariant electronic properties between metallic arc discharge SWCNT films of differing diameters.
