  • Abstract
    The influence of deposition parameters on microwave properties of BaxSr1-xTiO3 (BSTO) films deposited on alumina substrate has been investigated in a wide frequency range (1-30 GHz). The best combination of high tunability (n) and low losses (tan ¿) at room temperature was obtained for the 30% Ba content target. The best BSTO films exhibited n = 2.1 and tan¿=0.016 at 1 GHz and zero bias. This result is among the best reported for sputtered BSTO on alumina substrates.
