The applied methodology, which allows discerning between the intrinsic contribution, related to the field induced lattice distortion, and the extrinsic contributions, related to non-180° domain wall motion, is widely described in this work. The non-180° domain reorientation of the KNL-NTS piezoceramic is quantify from the integrated intensities of the 002 and 200 reflections obtained from line profile, while the shifts in peak position versus the applied electric field is used to obtain the lattice strain contribution.

The lattice parameters, atomic positions, dopant occupancy, and the second phase fraction were determined with high precision using a combined full pattern fitting via the Rietveld method. The results show that both 3 at.% and 9 at.% Si-doped HfO2 powder exhibit the monoclinic crystal structure with P 1 21/c 1 space group. Through the combined refinement, the crystal structure parameters, especially for the positions and occupancies of the lighter atoms, were more precisely determined compared to independent X-ray diffraction refinement. Although the ionic radius of Si4+ is smaller than Hf4+, with increasing Si occupancy, the unit cell volume slightly increases; possible mechanisms for this effect are discussed. Moreover, the refined results provide evidence of the existence of a non-equilibrium phase of HfxSi1−xO2. The second phase (SiO2) fraction is determined as 0.17 at.% for 3 at.% Si-doped HfO2 powders and 1.7 at.% for 9 at.% Si-doped HfO2 powders.}, journal={JOURNAL OF ALLOYS AND COMPOUNDS}, author={Zhao, Lili and Hou, Dong and Usher, Tedi-Marie and Iamsasri, Thanakorn and Fancher, Chris M. and Forrester, Jennifer S. and Nishida, Toshikazu and Moghaddam, Saeed and Jones, Jacob L.}, year={2015}, month={Oct}, pages={655–661} } @article{zhao_nelson_aldridge_iamsasri_fancher_forrester_nishida_moghaddam_jones_2014, title={Crystal structure of Si-doped HfO2}, volume={115}, number={3}, journal={Journal of Applied Physics}, author={Zhao, L.
