“…These thermal conductivity values are in line with other measurements on similar bulk PZT materials reported in the literature. Kallaev et al examined two types of PZT ceramics and found k ∼ 1.35 for PKR-8 and k ∼ 1.77 W m −1 K −1 for PKR-7M at 300 K. 25 Rivera-Ruedas et al 26 synthesized a series of PZT samples by mechanochemical activation of powder mixtures followed by thermal treatment. They found a larger range of thermal conductivity values with k between 0.55 and 2.1 W m −1 K −1 at room temperature, and no obvious trends were observed in thermal conductivity with the composition of the PZT or Pb oxide source.…”

We demonstrate the use of the time domain thermoreflectance (TDTR) technique towards understanding thermal transport in textured Pb(Zr,Ti)O3 (PZT) thin films grown by a sol-gel process on platinized silicon substrates. PZT films were grown with preferred crystallographic orientations of (100), (110), and (111). Grain orientation was controlled by manipulating the heterogeneous nucleation and growth characteristics at the interface between the film and the underlying Pt layer on the substrate. TDTR was used to measure both the PZT film thermal conductivity and the interface thermal conductance between the PZT and Pt as well as that between the PZT and an Al thermoreflectance layer evaporated on the PZT surface. We find a hierarchical dependence of thermal conductivity on the crystallographic orientation of the PZT films and observed differences in the thermal conductances between the Al-PZT and PZT-Pt interfaces for a varying degree of preferred orientations (100), (110), and (111). Thus, the technique based upon nanoscale thermal measurements can be used to delineate PZT samples with different crystallographic orientations. The thermal conductivities of the PZT films with different crystal orientations were in the range of 1.45-1.80 W m(-1) K(-1). The interface thermal conductance between the PZT and Pt layer was in the range of 30-65 MW m(-2) K(-1), while the conductance between the Al layer and PZT was in the range of 90-120 MW m(-2) K(-1). These interfacial conductances exhibit significant correlations to the texture of the PZT film and elemental concentration and densities at those interfaces.

“…is limited for PZT [25,26,81,82]. Thermal conductivity can have a significant effect on the performance of a device, both in the short term as it pertains to things like sensitivity, loss tangent and operational stability, but also in the long term concerning the reliability and degradation of the device over time.…”

The memories and moments that I've shared with all of you during my time in Charlottesville will be cherished for the rest of my life. A special thanks to all of my friends outside of Charlottesville that have lent their support from afar; the Gregoires, the Hardimans, the Foleys, the DeParis, the Donovans, the Brusos, the Mattons, Laura Day, Aleena Bando and the rest of the Worcester Homeloaf. Additionally, a huge thank you to my good friend and fellow WPI alumnus, Hans Jensen. Last but certainly not least, I would like to thank my amazing family and girlfriend, Caitlin, for all of the love and support that you have provided. To my parents, Jack and Robin: thank you for always being there for me both in good times and in bad, and for molding me into the man that I am today. I love you both so much and am so very proud to be your son. To my sisters, Lindsay and Mara: you are both so important to me and your love and support motivates me to be the best big brother that I possibly can. The three of us make a great team and I love you both so very much. To my extended family, all the Foleys, Mouchons and Collins: thank you all for all your love and support throughout my life. And to my girlfriend, Caitlin: words can hardly express how much I appreciate you being by my side and supporting me over the past seven years, especially the last five during my PhD. I love you so very, very much and look forward to our next adventure together! iii Contents Acknowledgements i cive field (±E c), saturation polarization (±P sat) and remanent polarization (±P r).
