We report on an extended use of the Fowler-Nordheim plot for energetic evaluation of charge transfers in vacuum electronics. First results explained clearly, the transition from field electron emission to plasma discharge is physically conditioned, especially in the case of higher emission currents.
The classical equations for describing the electron current density due to field and thermal emission from planar surfaces are unsuitable for modern nanometer-scale emitters. The planar equations are often presented in the form of Murphy and Good who, in their seminal paper [1], provided a method for deriving both the Fowler-Nordheim (FN) and Richardson-Schottky (RS) equations for field and thermal...
We report on the transition from field electron emission to plasma discharges. During an experiment with a miniaturized field emission electron source a plasma discharge accompanied by a luminous effect was observed. A novel graphical evaluation method was used to interpret and to compare the observed phenomenon.
Fluorine doping of ZnO nanowires was realized by using a biased CF4 plasma treatment. The morphology, work function, electrical characteristics and field emission properties of ZnO nanowires were investigated before and after CF4 plasma treatment. Though lowered work function and resistance were observed, the ZnO nanowires exhibit higher turn-on field after CF4 plasma treatment. The results were explained...
