SrBi3.98Dy0.02Ti4O15 (SBDT), a member of bismuth layer structure family, is prepared by solid state reaction method. XRD analysis shows the formation of single-phase compound with an orthorhombic structure. Complex impedance spectroscopy (CIS) and dielectric data are acquired from room temperature to 600°C over a wide range of frequencies. The results obtained from the impedance spectroscopy are analyzed, to understand the conductivity behavior of SBDT. Activation energies are evaluated from the data. The piezoelectric coupling factor, kp, is found to be 0.5.
