Broadband Dielectric Spectroscopy of Ruddlesden-Popper Srn+1TinO3n+1 (n = 1,2,3) Thin Films

Abstract

We explore the frequency-dependent relative permittivity of Ruddlesden-Popper series Srn+1TinO3n+1 n=1,2,3 thin films as a function of temperature and dc electric field. Interdigitated capacitors and coplanar waveguides were used to extract the frequency response from 500 Hz to 40 GHz. At room temperature, the in-plane relative permittivities 11 obtained for Srn+1TinO3n+1 n=1,2,3 were 42 3, 54 3, and 77 2, respectively, and were independent of frequency. At low temperatures, 11 increases and electric field tunability develops in Sr4Ti3O10.
