Popis: The gap length dependence of breakdown voltage for micrometer-scale gap in air and along dielectric glass surface with gap lengths from 5 to 50 μm, using a pair of conical trapezoidal electrodes with a radius of curvature of 20 μm, was investigated. The breakdown voltage of the gap along the glass surface with gap lengths from 5 to 15 μm was comparable to that for air gap. By increasing gap length of ≥ 25 μm, the breakdown voltage of the gap along the glass surface is considerably lower than that for air gap. From the discharge observations, discharge behavior turned from air gap discharge to surface discharge. The triple junction should be important role in this discharge transition.
