The DC bias dependence of the dielectric properties of BST thick films on YAlO3 substrates has been investigated for possible tunable microwave device applications. Rare earth aluminate (e.g. YAlO3) substrates were used to overcome the interfacial in

Tuning the temperature coefficient of resonant frequency (τf) in microwave dielectrics has been attributed to two main mechanisms: (i) dilution of the average ionic polarizability; (ii) the onset of an octahedral tilt transition above room temperatu

Developing a material with a temperature coefficient of the resonant frequency (TCF) of zero is probably the most difficult aspect of research into microwave dielectric ceramics. There are a host of high-quality-factor (Q) high-relative-permittivity

The microwave dielectric properties of the (SrxCa(1−x))n+1TinO3n+1 series have been measured. When n=∞, a linear decrease in TCF from +1647 (SrTiO3) to 859 (CaTiO3) MK−1 was observed as Ca content increased. This trend in TCF was attributed to

The microwave dielectric properties of the Sr x Ca 1− x TiO 3 , Sr n +1 Ti n O 3 n +1 and (Sr x Ca 1− x ) 3 Ti 2 O 7 series have been measured. TCF decreases from +1647 to +859 MK −1 as Ca content increases in the Sr x Ca 1− x TiO 3 series, d

Ruddlesden-Popper phases (general formula, A/sub n+1/Ti/sub n/O/sub 3n+1/) are composed of perovskite blocks separated and sheared by rock-salt structured layers along 1/2 [111]. Members of the Ruddlesden-Popper family, based on Ca and Sr, have been
