Reduction of the breakdown voltage in plasma panel discharge cells calls for electrode coatings with a high secondary-electron emission yield. MgO is most widely used in this field because of its high secondary-electron yield, which is primarily governed by ion-induced emission processes. To overcome the limits of ion-induced emission, opening an additional channel via photon-induced emission is a possible option. The present study shows that this is indeed feasible, with a photosensitive material showing a substantially higher effective secondary-electron emission coefficient γ[sub eff] when compared to state-of-the-art MgO electrode films. © 2003 American Institute of Physics.

    Cesium iodide (CsI) coated graphite is a good candidate for an electrode material of a thermionic power generation device due to its low work function. In this letter, a thermionic device with a nanometer-scale vacuum gap between a CsI coated graphite emitter and a collector will be investigated...

    Coincidence counting methods were used to examine the desorption of secondary ions from a CsI surface via keV atomic and polyatomic projectile impacts. A correlation between the emission of I- and CsI-2 secondary ions was attributed to the common chemical origin of the ions. The degree to which...
