Abstract

To inform the applicability of carbon nanotube networks for use as field effect transistors or as biosensors, we have run computer simulations in order to characterize the electrical properties of these networks, and specifically, how the resistance of these networks scales with the channel length for various amounts of metallic wires present in the networks. We find a trend that as the channel length increases, the resistance of the network increases as well. In addition, as the probability of metallic wires present in the network increases, the scaling factor of the resistance, m, increases at a larger constant rate with increasing channel length.
