Secondary electron emission coefficients in plasma display panels as determined by particle and fluid simulations
journal contribution
posted on 2008-02-25, 10:26 authored by S.S. Yang, S.M. Lee, Felipe Iza, Jae Koo LeeThe secondary electron emission coefficient (γse) of ions and excited species
in a plasma display panel (PDP) was studied by means of 2-dimensional
fluid and 1-dimensional particle-in-cell Monte Carlo collision simulations.
Relations between the driving voltage and the luminous efficiency observed
in experiments are reproduced at low and high Xe concentrations.
Agreement between experiments and simulations, however, requires careful
selection of the γse of ions and excited species. The trend of the efficiency as
a function of the driving voltage is particularly sensitive to the γse of Xe
excited species. For the conditions typically encountered in PDP cells (pd=
1–10 Torr cm), the dependence of the γse on the energy of impinging ions
can be neglected in discharges of pure gases. This is a consequence of
multiple charge exchange collisions in the cathode region. In Xe–Ne
mixtures, however, the ion energy distribution function on the cathode
depends on the mixture ratio. Typically more energetic ions can reach the
cathode in gas mixtures and the γse is enhanced.
