Abstract Electronics miniaturization motivates gas breakdown predictions for microscale and smaller gaps, since traditional breakdown theory fails when gap size, d, is smaller than ∼15 μm at atmospheric pressure, p{sub atm}. We perform a matched asymptotic analysis to derive analytic expressions for breakdown voltage, V{sub b}, at p{sub atm} for 1 nm ≤ d ≤ 35 μm. We obtain excellent agreement between numerical, analytic, and particle-in-cell simulations for argon, and show V{sub b} decreasing as d → 0, instead of increasing as predicted by Paschen's law. This work provides an analytic framework for determining V{sub b} at atmospheric pressure for various gap distances that may be extended to other gases.
