Recent studies have shown that, in microscale electrode gaps, the traditional Paschen's curve fails as the left branch sharply decreases with electrode spacing, thus resulting in the modified Paschen's curve. This deviation from Paschen's curve is attributed to ion-enhanced field emission and notably breaks pressure times distance (pd) scaling. Here, 1-D particle-in-cell/Monte Carlo collisi...
