The mechanism of the gaseous breakdown in the electrode system with one-dimensional (1D) nanomaterial film is investigated. The hypothesis is suggested that the functionality of the 1D nanostructures in the breakdown is the averaged flux-convergence-effect of multiple nanoelectrodes to the electric field distribution, which leads to a convergence band model for discharge modeling. Theoretical deductions are examined by experiments in air and N(2) at pressures (p) near the Paschen's minimum with gap sizes (d) of similar to 335 mu m and pd range of 0.01-1 Torr cm. It is suggested that the increased efficiency of the secondary processes and the discharge's lateral spreading may characterize the breakdown mechanism in electrodes with 1D nanostructures.
