Capacitors were then fabricated from the BST thin films based on coplanar interdigital electrodes (CIEs) and parallel-plate electrodes (PPEs). The dielectric properties of the BST film with CIE and PPE were investigated and compared over a wide frequency range from 100 Hz to 10 GHz. The dielectric dispersion in PPE configuration, caused by the interfacial polarization in film/electrode interfaces, exhibited a strong dependence on frequency. However, the permittivity εCIE in CIE configuration shows a gentle variation with the frequency indicating interfacial polarization substantially suppressed. The influence upon the dielectric properties of the columnar BST grains due to the use of different forms of electrodes was discussed. © 2009 IOP Publishing Ltd.||Source Title:||Journal of Physics D: Applied Physics||URI:||http://scholarbank.nus.edu.sg/handle/10635/115066||ISSN:||00223727||DOI:||10.1088/0022-3727/42/6/065411|
