Abstract:

Transparent conductive networks are important for flexible electronics and solar cells. Often interwire (junction) cond. is the limiting factor for network cond. and can be improved by various treatments. The cond. of individual junctions in a single walled carbon nanotube network was measured by conductive at. force microscopy before and after exposure to nitric acid. The measurements show that this exposure improves the cond. of each one of the junctions within the network. The results suggest that the acid improves the cond. by p-type charge transfer doping and by surfactant degrdn. [on SciFinder(R)]
