Under a high electrical field, field emission current may be significantly enhanced by positive ions very close to the cathode surface. In addition to distorting the potential field to both lower and thin the potential barrier, the ion can also induce resonant tunneling, which can be a major factor in the emission current. In this study, resonant tunneling behavior has been investigated using a simple...
It has been shown that field emission is an important mechanism in emerging microplasma devices. Ions formed by electron impact ionization that are very close to the cathode may bring significant enhancement to the emission current by both resonant and non-resonant processes. In this work, we numerically solve the one-dimensional Schrödinger's equation in the presence of an ion approaching the surface,...
A dc microplasma jet in flowing argon (Ar) gas is used to electrolyze aqueous sodium chloride (NaCl) solutions. Electrolytic reactions at the plasma-liquid interface make the solution more basic and result in H2 gas evolution. The pH change is visualized using a pH sensitive dye, which becomes dark green under basic conditions. The basic solution created at the plasma-liquid interface is subsequently...
