  1. Time-resolved X-ray diffraction during application of dynamic electric fields to measure domain switching directly Synthesis of Pb(Zr,Ti)O3-based ceramics with various dopants and Zr:Ti ratios Fracture surface of La-doped PZT with Zr:Ti of 60:40. The marker is 5 μm wide. Crystallographic changes as a function of time during application of an electric field. Data collected on a time-resolved laboratory diffractometer. Macroscopic property measurements to assess the degree of domain switching Macroscopic piezoelectric (d33) measurements of La-PZT as a function of Zr:Ti ratio and electric field amplitude. Time-resolved structure-property relationships in piezoelectric ceramicsJacob L. Jones (University of Florida),DMR 0746902 The primary goal of this CAREER program is to establish a new research and education framework in which to probe the relationship between microscale and nanoscale structural mechanisms and macroscopic properties in the time domain. Thus far, this has involved:

  2. A collaboration with Sandia National Laboratories using the new diffractometer reveals the sequence of crystallization in PLZT thin films as a function of time and temperature in situ. A major component of this project involves the development and utilization of a local time-resolved X-ray diffractometer as well as the use of synchrotron diffraction facilities. The time-resolved laboratory diffractometer has been commissioned and we have started working with international collaborators. A student preparing time-resolved X-ray diffraction measurements at the European Synchrotron Radiation Facility (ESRF). A visualization program for 3rd-rank tensors was written and presented at the International Symposium on Applications of Ferroelectrics (ISAF). It is available for free on the PI’s website. Components of the in-house laboratory diffractometer for research and education.
