NSUF 18-1459: Post-irradiation Piezoelectric Property Characterization of Radiation-Tolerant Piezoelectric Materials
The objective of this research is to quantify the dielectric and electromechanical properties of irradiated piezoelectric materials (bismuth titanate and aluminum nitride) using atomic force microscopy. This RTE proposal addresses open questions on piezoelectric material property variations with irradiation (especially at doses in excess of 10^20 neutrons/cm^2) identified in the published research. The proposed research is focused on examining previously irradiated BiT and AlN samples using an atomic force microscope (AFM) to quantify changes in piezoelectric and dielectric properties under irradiation. The proposal leverages an AFM (recently installed at the RPL facility at Pacific Northwest National Laboratory) for examining irradiated materials, and takes advantage of the availability of the irradiated specimens that have been recently received at the Idaho National Laboratory. The resulting measurements of piezoelectric and dielectric properties will confirm available data in the literature and provide some of the first data on these properties under high-neutron dose conditions. The information may be applied for improving the material selection and design of radiation-tolerant sensors for in-pile or in-reactor measurements. The research will be conducted over a 6 month period after project award.
