Random 2D nanowire networks: Finite-size effect and the effect of busbar/nanowire contact resistance on their electrical conductivity

We have studied the resistance of two-dimensional random percolating networks zero-width metallic nanowires (rings or sticks). toke into account nanowire per unit length, junction (nanowire/nanowire contact) resistance, and busbar/nanowire contact resistance. Using a mean-field approximation (MFA), we derived total nanoring-based as function their geometrical physical parameters. proposed way accounting for contribution toward network The MFA predictions been confirmed by our Monte Carlo (MC) numerical simulations. Our study evidenced that has significant effect on electrical conductivity when dominates over wire
