A four-way switch promises greater tunability of layered materials
Nov. 19, 2019—A scientific team from Vanderbilt University and the Department of Energy’s Oak Ridge National Laboratory has made the first experimental observation of a material phase that had been predicted but never seen. The discovery breaks new ground in the study of ferroelectricity, a characteristic of certain dielectric materials used in high-technology applications. The team made...
