Intrinsic and effective secondary electron emission coefficients in AC plasma display panel

Ion-induced secondary electron emission from the MgO protecting layer of an AC plasma display panel (AC-PDP) and the successive back-scattering of sec ondary electrons toward the cathode due to high gas pressure have been stud ied theoretically. A correlation between the intrinsic secondary electron e mission coefficient (gamma (i)) and the TvIEO surface properties such as ba nd gap energy and defect states in the band gap was found. The behavior of the effective secondary electron emission coefficient (gamma (eff)) of vari ous ion species as a function of the reduced electric field (E/P) has also been investigated. These relationships can be applied to AC-PDP manufacturi ng in order to enhance the luminous efficiency and to reduce the breakdown voltage of AC-PDPs.
