Proximity Effects in van der Waals Materials

 

Igor Žutić, University at Buffalo

 

Advances in heterostructures and atomically thin van der Waals materials, such as graphene, suggest a novel approach to systematically design materials. A given material can be transformed through proximity effects whereby it acquires properties of its neighbors, for example, becoming superconducting, magnetic, topologically nontrivial, or with an enhanced spin–orbit coupling [1]. Such proximity effects not only complement the conventional methods of designing materials by doping or functionalization, but also can overcome their various limitations. In proximitized materials, it is possible to realize properties that are not present in any constituent region of the considered heterostructure. While the focus is on magnetic proximity effects with their applications in spintronics [2-4], the outlined principles also provide a broader framework for employing other proximity effects to tailor materials and realize unexplored phenomena.

Igor Žutić is a Professor of Physics at the University at Buffalo. He received his Ph.D. in theoretical physics at the University of Minnesota in 1998, after undergraduate studies at the University of Zagreb, Croatia. Žutić’s work spans topics from high-temperature superconductors, Majorana fermions, unconventional magnetism, proximity effects, and two-dimensional materials, to prediction of various spin-based devices that are not limited to the concept of magnetoresistance used in commercial application for magnetically stored information. Some of these devices, such as spin diodes, spin solar cells, spin transistors, and spin lasers have already been experimentally demonstrated. He has published over 100 refereed articles and given over 140 invited presentations on spintronics, magnetism, and superconductivity.  Igor Žutić is a recipient of 2006 National Science Foundation CAREER Award, 2005 National Research Council/American Society for Engineering Education Postdoctoral Research Award, and the National Research Council Fellowship (2003-2005). He is a Fellow of American Physical Society.
