Dielectric Properties of Pb1-xBaxZrO3 Thin Films with Higher Barium Content

Article Preview

Abstract:

The dc bias and temperature dependence of dielectric properties of Pb1-xBaxZrO3 (PBZ) thin films with higher x (x=0.6, 0.7, 0.8 and 1) were investigated in detail. The results indicated that Pb0.4Ba0.6ZrO3 films possessed a moderate tunability of 32.3% and a higher figure of merit of 53.8, which were measured at 100 kHz and at room temperature. Moreover, Pb0.4Ba0.6ZrO3 films exhibited a smaller temperature coefficient of capacitance TCC-20-90= -1390 ppm/oC.
