ABSTRACT
Multiferroic materials, such as BiFeO3, allow for the electric-field control of magnetization because of their magnetoelectric coupling effect. They have been studied extensively for the rich underlying physics and potential applications in future spintronic devices. However, research on conventional multiferroic materials have encountered serious obstacles, e.g., small coupling coefficients of Type-I multiferroics and low temperature/high conductivity of Type-II multiferroics.
Recent developments in 2D ferroelectrics open a new paradigm in the field. After a brief review of our previous work on BiFeO3, I will talk about the unique properties of 2D ferroelectric materials and the opportunities they brought in term of electric-field control of electron spin and magnetization.
BIOGRAPHY
Professor Junling WANG obtained his B.S. degree from Nanjing University, China in 1999, and Ph.D. degree from University of Maryland, College Park in 2005. After a short postdoc training at PennState University, he joined Nanyang Technological University, Singapore as an Assistant Professor in 2006. He was promoted to Associate Professor with tenure in 2011 and Full Professor in 2017. In 2020, he joined Southern University of Science and Technology (SUSTech), China as a Chair Professor.
Professor Wang’s research activities focus on 3D and 2D ferroelectric and multiferroic materials. These materials possess a wide range of exotic properties such as ferroelectricity, ferromagnetism, and multiferroicity. The long-range orders and cross-couplings between them lead to fascinating physics and various applications. He has published over 160 papers in high impact journals, including Science, Science Advances, Nature Materials and Nature Communications. His work has been cited more than 19600 times with an H-index of 58 (google scholar).
