Calculation of Secondary Electron Emission Yield From MgO Surface
Secondary electron emission yield values for rare-gas particles (He, Ne, Ar, Kr, and Xe ions of atoms and molecules, metastable atoms, and excimers) of MgO deposited under optimum conditions for the highest values were calculated assuming the Auger transitions between the valence band, and the (oxygen ion vacancy + two electrons) and + (oxygen ion vacancy + one electron) centers in the MgO surf...
متن کاملFirst-principles study on secondary electron emission of MgO surface
We theoretically investigate secondary-electron-emission properties of MgO when noble gases are incident on the surface. We consider both potential and kinetic emission mechanisms. For the potential emission through Auger neutralization, densities of states and vacuum level are obtained from the first-principles calculations. It is found that secondary-emission coefficients decrease in the foll...
متن کاملSecondary-Electron-Emission Instability in a Plasma
A 200-eV electron beam is incident on an electrode in a laboratory plasma. The emission of secondary electrons produces a region of negative differential resistance in the current-voltage characteristic of the electrode. Spontaneous dynatron oscillations are driven by the negative differential resistance when a resonant circuit is placed in series with the electrode. The instability is driven b...
متن کاملCharacteristics of a micro dielectric barrier discharge ignited by a cold cathode with high ion-induced secondary electron emission for plasma display panel
We present here measurements of plasma display panel PDP ignited by SrO and SrCaO cold cathodes with high yield of ion-induced secondary electron emission high i . SrOand SrCaO-cathode PDPs attain high luminous efficacy at low applied voltage, where the breakdown voltage is 30% lower than that of ordinary MgO-cathode PDP. Current and emission measurement clearly demonstrates that SrOand SrCaO-c...
متن کاملGasification from Surface during Discharge and Thermal Process in Plasma Display Panel (PDP)
− Plasma display panel(PDP) uses the mixture of inert gases to generate a discharge inside display pixels. Inside of PDP, there exists highly reactive conditions in the gap between two glass panels. Chemical properties of MgO layer and phosphor have been investigated as a function of discharge and thermal process. Impurities such as CO, CO2, OH and H2O in discharge region may deteriorate the ch...
