Title: Polar Nanoregions and Relaxors: How Nanoscale Disorder Leads to Enormous Electromechanical Response (438th Brookhaven Lecture)

Relaxors is the name given to a special class of materials called relaxor ferroelectrics. Xu will describe a series of experiments done by BNL researchers with collaborators from Stony Brook Universitmore »y, Johns Hopkins University, and the National Institute of Standards and Technology, to discover why relaxors have such an exceptional electromechanical response. The explanation is dependent on "polar nanoregions" -- tiny, nanometer-scale regions within the relaxors. The team established a link between polar nanoregions and the relaxors' ability to deform in response to an electric field, or to have a pulse of electric current induced by a deforming physical force. This understanding promises to lead to more improvements to relaxor materials for an even greater variety of applications.« less
