Functional Ceramics

The focus of the Functional Ceramics research group is the experimental characterization of mechanical and electrical properties of novel perovskite materials, particularly the influence of external fields on the structural phase transformations and conductivity as well as temperature-dependent electromechanical behavior.

Perovskite-structured ceramics are commercially important oxides that are used in numerous actuation, sensing, and energy applications due to their wide-ranging functional material properties, such as ferroelectricity, ferromagnetism, superconductivity, colossal magnetoresistance, and ionic conductivity.

In order to realize such measurements, we have developed a number of unique experimental arrangements, which allow us to characterize the large and small signal electromechanical response of materials over a large temperature range (–150 to 800 °C) under large external mechanical and electrical fields.
