Abstract
Voltage-tunable dielectric materials are widely used for microwave-frequency signal processing. Among tunable dielectric thin films, (SrTiO3)nSrO Ruddlesden-Popper (RP) superlattices have exceptionally low loss at high frequencies. This paper reports the first realization of resonators, a ubiquitous building block of microwave components, fabricated on RP films, and an analysis of their static and dynamic tuning behavior. The resonators have approximately 2.5 % tuning of the resonance frequency at room temperature and 20 % tuning at 200 K, and a tuning time scale of less than a nanosecond, which is limited for the current measurements by the circuit rather than material propertiesCitation
