Physical Electrostatics of Small Field Emitter Arrays/clusters

This paper aims to improve qualitative understanding of electrostatic influences on apex field enhancement factors (AFEFs) for small field emitter arrays/clusters. Using the "floating sphere at emitter-plate potential" (FSEPP) model, it re-examines the electrostatics and mathematics of three simple systems of identical post-like emitters. For the isolated emitter, various approaches are noted. ...

Field emission properties of individual zinc oxide nanowire field emitter

The authors report the field emission FE properties of individual ZnO nanowire field emitters. ZnO nanowire field emitter directly grown on a Pt tip showed a much better field emission current delivery than the attached nanowire emitters due to better contact properties. The emission current and field emission microscopy pattern of the ZnO nanowire are strongly influenced by adsorbates. After t...

Poly-Diamond Gated Field-Emitter Display Cells

A microchip containing gated field-emitter display (FED) cells is designed and fabricated using vapor-deposited ptype polycrystalline diamond films and employing an integrated circuit (IC)-compatible diamond film technology on oxidized 4in Si wafers. Current–voltage (I V ) data, measured in a diode configuration at 10 6 torr, show Fowler–Nordheim (F–N) field emission behavior. A 1 4 pixel diamo...
