Research
Electromechanically-Active Materials
We probe the fundamental science of ferroic materials, as it pertains to the mechanisms of intrinsic and extrinsic contributions to the functional response of these materials. Specifically, we probe the defect-defect interactions between domain walls, point, line and area defects.
We also explore novel mechanisms and new processing approaches for enhanced electromechanical response at the micro and nanoscale (increased or invariant response with decreasing size). Of special interest are exploration of new material composition unstable in bulk form, understanding of the mesoscale origins of the giant electromechanical response in relaxor-ferroelectric solid solutions, radiation effects on the functional response of ferroelectric materials, and design of compositions for high energy storage applications. Correlation of the micro- and macro-scopic responses are other areas of interest within this research thrust.
In-Situ and Operando Characterization at the Mesoscale
This thrust hinges on design of energy discovery platforms: appropriately created micro- and nano-structures to enable in-situ and operando characterization at multiple length scales (e.g. piezoresponse force microscopy and electron microscopy, as well as macro-scale characterization techniques), while resulting in enhanced compatibility with mathematical and finite element modeling of the same. The coupled theoretical and experimental results allow a unique vision into the electro-chemo-mechanical processes with an unprecedented resolution (from tens of nanometers to few microns) over many orders of magnitude overall length-scales (tens to hundreds of microns). Specifically, we leverage machine learning approaches to separate physical and chemical contributors and understand correlation across properties and length scales in materials.
Far-from-Equilibrium Processing Approaches
We explore new processing approaches for fabrication of micro and nanoscale complex oxide materials, with special focus on enabling technologies for fabrication of micro- and nano-electromechanical systems (MEMS and NEMS), and increased compatibility with CMOS processing for full integration and final miniaturization. These processing approaches are far-from-equilibrium and therefore result not only in substantially microstructure changes but also large variations of the final functional properties of the material.
We probe the resulting properties of the materials, specifically targeting the physics of these complex oxides at the mesoscale, through integration of macro and microscopic characterization techniques. Our final goal is to create a processing design space that is uniquely correlated with the desired final functional responses.
