Abstract:

A microscale gas breakdown device includes a first surface and a second surface. The first surface and the second surface define a gap distance. The device includes a perturbation on the first surface or the second surface. The perturbation is defined by a height value and a radius value. The device includes a current source or a voltage source configured to apply a current or a voltage across the first surface and the second surface. In response to the current or the voltage being applied, a resulting discharge travels along a first discharge path in response to being exposed to a high pressure and a second discharge path in response to being exposed to a low pressure.
