Center Overview

The Center for Dielectrics and Piezoelectrics (CDP) supports industries that develop and manufacture materials and devices that underpin the functionality of consumer electronics, medical ultrasound, wireless communication devices, electrical vehicles, and a variety of other important technology areas. CDP supports scientific progress in these areas through the development of new materials, processing strategies, electrical testing, and nanoscale characterization and modeling methodologies. Its research addresses a broad and diverse number of scientific challenges across the dielectric- and piezoelectric-based industries. CDP’s goals are to:

  • Serve as a leading international center dedicated to improving the science and technology of dielectric and piezoelectric materials and their integration into devices.
  • Perform innovative interdisciplinary research that will lead to novel breakthroughs in dielectric and piezoelectric materials.
  • Educate graduate students and postdoctoral scholars who will become leading members of the research community with a minimal learning curve.
  • Develop unique measurement, modeling, and characterization infrastructure to support the industry.

CDP faculty are international leaders and have unique capabilities to drive research innovations for next-generation dielectric and piezoelectric materials and devices. CDP engages companies across the supply chain, those that manufacture dielectric and piezoelectric materials, component manufacturers, and end users.

Research Focus

Innovations in the dielectric and piezoelectric industrial sectors often arise from research advances in materials chemistry, synthesis, and manufacturing that enable the creation of new materials and improved device functionality. To support innovations, CDP has organized its research portfolio into five technical topics, which are unified by a common theme of harnessing, controlling and optimizing polarization phenomena for energy storage, transduction, and management. Those five topic areas in which CDP researches are:

  • Capacitors for extreme environments, to develop new dielectrics capable of handling increased voltages and operation temperatures in application areas such as automotive, power electronics, and aerospace/defense systems.
  • Miniaturized complementary metal oxide semiconductor-compatible piezoelectrics actuators, high-quality factor resonators, and lead-free piezoelectric ceramics that can handle aggressive driving conditions.
  • High-energy density capacitors for electric vehicles and wearable electronics.
  • Dielectrics for low-temperature and flexible substrates for foldable and stretchable electronics. 
  • Nonlinear and high-frequency dielectrics for 5G communications, including quantitative high-frequency dielectric characterization, new manufacturing technologies, temperature-stable high-quality factor dielectrics at high frequencies, and high-reliability integrated tunable capacitors.

 

The research is supported by unique expertise and facilities in five cross-cutting research areas:  

  • Computational modeling.
  • Life cycle analysis. 
  • Nanoscale characterization.
  • Property and reliability characterization.
  • Synthesis and processing science.
