Conductivity Enhancement of Transparent 2D Carbon Nanotube Networks Occurs by Resistance Reduction in All Junctions
Transparent
conductive networks are important for flexible electronics
and solar cells. Often interwire (junction) conductivity is the limiting
factor for network conductivity and can be improved by various treatments.
The conductivity of individual junctions in a single walled carbon
nanotube network was measured by conductive atomic force microscopy
before and after exposure to nitric acid. The measurements show that
this exposure improves the conductivity of each one of the junctions
within the network. Our results suggest that the acid improves the
conductivity by p-type charge transfer doping and by surfactant degradation
