Abstract

Lead strontium zirconate titanate (PSZT) solid solutions are investigated for low-process temperature, tunable dielectric applications. PSZT films of three compositions (40%, 50% and 55% Sr) are prepared via a chemical solution deposition route. AU films display paraelectric properties at room temperature and dielectric losses below 0.05 under field. Dielectric tunability is demonstrated to increase with annealing temperature. However, even films crystallized at 650°C have tunabilities of at least 24% at 400 kV/cm, with films of the (Pb_0.45Sr_0.55)(Ti_0.7Zr _0.3)O₃ composition exhibiting a tunability of 57%. Such dielectric tunability approaches typical values for low-temperature deposited (Ba,Sr)TiO₃ films crystallized at 900°C.
