Ferroelectric domain walls are promising quasi-2D structures that can be leveraged for miniaturization of electronics components and new mechanisms to control electronic signals at the *** the significant progress in experiment and theory,however,most investigations on ferroelectric domain walls are still on a fundamental level,and reliable characterization of emergent transport phenomena remains a challenging task.

＜正＞In recent years,with the growing demand for global environmental protection, lead-free materials have gained considerable *** such most promising lead-free material is Sodium bismuth titanate,Na1/2bi1/2TiO3（NbT）,with AbO3 perovskite type structure discovered by smolenskii et al[1].The NbT composition exhibits a strong ferroelectricity,high Curie temperature and shows diffuse phase transition（DPT）,it has been considered to be a good candidate of lead-free ceramics as a substitute for lead-based materials （e.g.,PZT）,which have been widely used for ultrasonic generators,actuators,filters,and other electronic devices[2,3].In addition to the DPT near 3200C,two more phase transitions were reported at 2300C and between 5000C -*** peculiar phase transition behaviour of NbT has attracted considerable ***,pure NbT has a drawback of high conductivity that leads to problems in the poling *** improve its structural and electrical properties, the composition of NbT was modified by dopants such as rare-earth elements in small amounts （i.e Ce,Er,Eu,La,and sm）[4].This type of dopants may control phase transition,the relaxor ferroelectricity and electro- mechanical properties would be strongly correlated to the vacancies and their impact on polarization of the *** the present work,the effect of doping Praseodymium,Pr3+ at the A-site on the dielectric behaviour and also the phase transitions in NbT,have been studied.A polycrystalline ceramic（Na0.5bi0.5）0.8875Pr0.075TiO3 has been prepared by a high temperature solid state reaction *** formation of single phase with tetragonal structure has been confirmed by room temperature x-ray diffraction studies. Scanning electron micrographs of sintered sample were recorded at room temperature to study the surface morphology and the grain distribution over the *** response of this composition have been studied as function of temperature（rt-5800C） and frequency （45Hz-5MHz）,Imp
