Electrical and optical performance of PbZr_0.4Ti _0.6O₃ optical microcavity derived from one single chemical solution

Fabry-Perot optical microcavity, comprising of two quasiperiodic PbZr _0.4Ti_0.6O₃ multilayers and a dense PbZr _0.4Ti_0.6O₃ space layer, has been fabricated on the F-doped transparent conductive tin oxide thin film by using one single precursor. The obtained multilayer system displays excellent dielectric, ferroelectric, and optical properties simultaneously. It has a dielectric constant of 629 and dielectric tunability of ∼60% at 1 MHz, an average remanent polarization of ∼46.9 μC/cm², and a quality factor of ∼44, rendering its promising applications in dynamic random access memories, microwave tunable devices and integrated optoelectronics, and an alternative matter system for studying cavity quantum electrodynamics.
