Nanowire networks (NWNs) are promising candidates for a range of material and device applications. Although much is known about the percolation behaviour of nanowire systems especially in polymer composites, the inherent connectivity in high density NWNs is not at all understood. Such networks are comprised of wires that are well connected but individual wires are frequently separated by surface passivation...
We have prepared thin films of arc discharge single walled nanotubes by vacuum filtration. For film thicknesses greater than 40nm, the films are of high optical quality; the optical transmission varies by <2% over the film area when measured with a spatial resolution of 4μm. However, the films become spatially non-uniform for film thickness below 40nm. The in-plane DC conductivity correlates with...
