We study the dielectric strength of vacuum gaps of under 100 nm. We find their dielectric strengths to have a power law dependence on the gap size. We apply this power law to find that the dielectric strength of a vacuum gap of 10 nm between two tungsten electrodes is 6.5 V/nm. The dielectric strength can be used to compute the maximum energy density, charge density, and power density. For tungsten, the maximum volumetric energy density is 190 MJ/m3. Nano vacuum gaps can discharge in 10… Expand
