Microscopists detect quasi-chiral walls in ferroelectric materials

Jülich, 13 September 2016 - The atomic structure of ferroelectric materials is more diverse than previously assumed. An international research team made this discovery through experiments with electron microscopes carried out at the Ernst Ruska-Centre (ER-C) in Jülich. The ER-C is a leading centre for ultra-high-resolution electron microscopy. Their discovery could open up new fields of applications for a particular class of polarised crystals: so-called ferroelectric materials. The researchers believe these applications could range from the development of miniaturized pressure sensors and the tiniest of transistors through to highly integrated storage media (Nature Communications, DOI: 10.1038/ncomms12385).
