Two-dimensional analysis of data writing on a dielectric layer surface by a microdischarge working as a regulated output/storage device

Data writing on a dielectric layer surface by a microdischarge is investigated using a two-dimensional numerical analysis. A microdischarge, working as a regulated output/storage device, accumulates a regulated amount of charge on the surface of an adjacent dielectric layer. The charge density depends on the voltage applied on a writing electrode, located externally on the opposite side of the dielectric layer. Data writing as a charge accumulation is completed not during the discharge but in the phase of afterglow. As a result, a regulated electric field is imposed on the dielectric layer. The charge density dependence on its polarity is also investigated.
