Field electron (FE) emitters may be prepared by coating a metallic emitter or a carbon‐fibre
emitter with a layer of dielectric material. Such 'composite'emitters are of interest for both …

In this work, the field electron emission from oxidized copper emitters was studied by aging
with radii in the range of 80–300 nm. The samples were prepared by an electrochemical …

On‐chip electron sources with low pressure‐sensitivity and outstanding emission
performances under rough vacuum are highly desired for developing miniature fully …

Abstract Since the Great East Japan Earthquake in 2011, there has been a growing interest
in energy conservation all over the world. To build a society centered on renewable energy …

Design, fabrication, and characterization of Pt-coated, self-aligned, and gated Si field
emission arrays are reported. Arrays of 320000 tips with 10 m pitch are employed to emit …

A novel self-aligned process was developed to fabricate gated Si field emission devices. At
a gate voltage of 100 V, the emission current from an array of 100 tips increased from 283 to …

Molybdenum is a transition metal, known for its coarse nature and high hardness. In the
present study, a 99.95% pure molybdenum material was used to fabricate nano-and micro …

Titanium nitride (TiN) thin film coatings were studied by field emission microscopy and
spectroscopy. Coated tungsten tips were found to be capable of emitting extremely high …

In this study, two different methods are used to investigate carbon black as a cold field
electron emitter. The first method is to incorporate carbon black into a specially designed …

Tungsten based microemitter tips have been prepared both clean and coated with dielectric
materials. For clean tungsten tips, apex radii have been varied ranging from 25 to 500 nm …
