| Abstract: | A low temperature sintered multilayer ceramic substrate has been prepared consisting of a very high dielectric constant trinary system PMN-PT-PCW ceramic thick film insulating layer,Ag/Pd alloy internal electrodes and a ceramic base.The ceramic thick film and the internal electrodes are fabricated by casting tape process and silk-screen process,respectively. The relative dielectric constant of the ceramic thick film is over 14 000 with the loss of about 1 % at room temperature,and figure of merit of above 80 μC/cm2.The relationship between threshold voltage and dielectric properties are derived theoretically.Two types of CIEL devices with ZnS:Mn as an active layer have been manufactured and their EL characteristics are compared as well. |
