Field emission properties of sharp tungsten cathodes coated with a thin resilient oxide barrier
Original language description
This research is aimed towards more in-depth understanding of field emission properties of tungsten single tip field emitters (STFEs) coated with tens of nanometer thin barrier of selected refractory oxides such as Al2O3. Introducing the additional barrier into metal-vacuum interface system of the emitter can be beneficial for an improvement of its performance. The pristine tungsten emitters were prepared using a two-step electrochemical drop-off etching technique. Thin oxide barriers were prepared by using low-temperature atomic layer deposition (ALD). Field emission was studied in field emission microscope (FEM) working in UHV vacuum (< 1x10(-7) Pa), experimental field emission data were analyzed by the so-called Murphy-Good plots, revealing the non-orthodox behavior of the prepared emitters.
