15 صفحه اولEmittance of a field emission electron source
An analytical formula of the emittance of a field emitter is given. In contrast to thermal and photoemission, such a formula contains complexity due to the multidimensional nature of the source. A formulation of emittance is given for oneand three-dimensional 3D field emitters. The 3D formulation makes use of the point charge model of a unit cell emitter coupled with a trajectory analysis to fo...
متن کاملNano-structural Characterization of Post-annealed ZnO Thin Films by X-ray Diffraction and Field Emission Scanning Electron Microscopy
ZnO thin films were deposited on Si(400) substrates by e-beam evaporation technique, and then post-annealed at different annealing temperatures (200-800°C). Dependence of the crystallographic structure, nano-strain, chemical composition and surface physical Morphology of these layers on annealing temperature were studied. The crystallographic structure of films was studied using X-Ray Diffracti...
متن کاملField - Free and Field - Stimulated Electron Emission from Solids
Electron irradiation of solids produces a backemission of secondary electrons (energies between 0 and 50 eV) and re ected primaries (energies between 50 eV and that of the incident beam). For insulators, it is shown that an externally applied positive electric eld penetrating into the solid material, energizes electrons generated by the primary irradiation and enables them to travel back to the...
متن کاملNoble Metal/W(111) Single-Atom Tips and Their Field Electron and Ion Emission Characteristics
We have developed a simple, reliable and reproducible method for preparing single-atom tips. With electrochemical techniques, a very small amount of a noble metal is plated on the surface of a clean Wh111i tip. Upon annealing the tip at an appropriate temperature in vacuum, a three-sided {211} pyramid with a single-atom sharpness is formed spontaneously at the tip apex by adsorbate-induced face...
