Physics researchers at the University of North Florida’s Atomic LEGO Lab discovered a new electronic phenomenon they call “asymmetric ferroelectricity.” The research led by Dr. Maitri Warusawithana, UNF physics assistant professor, in collaboration with researchers at the University of Illinois and the Arizona State University, demonstrated this phenomenon for the first time in engineered two-dimensional crystals.<\/p>\n

This discovery of asymmetric ferroelectricity in engineered crystals comes exactly 100 years following the discovery of ferroelectricity in certain naturally occurring crystals. Ferroelectric crystals\u2014crystals that show two equal bistable polarization states\u2014are now used in many high-tech app<\/a>lications including solid-state memory, RFID cards, sensors and precision actuators.<\/p>\n

Utilizing atomic-scale materials design, the team of researchers has demonstrated a qualitatively new phenomenon, asymmetric ferroelectricity, for the first time. These engineered crystals lead to an asymmetric bi-stability with two unequal stable polarization states in contrast to a natural ferroelectric.<\/p>\n

Warusawithana hopes this first observation of asymmetric ferroelectricity achieved through materials-by-design will further research on tailored electronic properties and may find its way into interesting technological applications.<\/p>\n\n
