Statistical property of the effect of Au nanoparticle decoration on the carbon nanotube network

Statistical analysis of the change in electrical characteristic of single-walled carbon nanotube (swCNT) network after the decoration of Au nanoparticles (NPs) is presented. We have fabricated 100 unitary swCNT network devices on a single chip employing a concentric electrode array by swCNT dip-coating and thermal evaporation of Au. The experimental results show that the decoration of Au-NP on the swCNT network can decrease not only its resistance but also variation in the resistance distribution. Remarkably, we have found that the change in electrical characteristic is correlated with the resistance value of the bare swCNT network.
