Ferroelectric materials react unexpectedly to strain
Chicago IL (SPX) Jun 15, 2016
Up until recently, researchers thought they had the behaviors of ferroelectric materials mostly figured out. "The conventional wisdom is that you can put almost any material under mechanical stress, and provided the stress is coherently maintained, the material will become ferroelectric or exhibit an electrical polarization," said James Rondinelli, assistant professor of materials science and engineering at Northwestern University's McCormick School of Engineering. "If you apply similar stresses t ... read more
