2D Magnets: Discovery, Challenges, and Opportunities


Magnetism, one of the most fundamental physical properties, has revolutionized significant technologies such as data storage and biomedical imaging, and continues to bring forth new phenomena in emerging materials and reduced dimensions. The recently discovered magnetic 2D van der Waals materials (hereafter abbreviated as “2D magnets”) provide unprecedentedly ideal platforms to enable the atomic-thin, flexible, lightweight magneto-optic and magnetoelectric devices. The seamless integration of 2D magnets with dissimilar electronic and photonic materials further opens up exciting possibilities for previously-unachieved material properties and device functionalities. In this talk, I will speak on our discovery of the first 2D ferromagnet, analyze the current progress and the existing challenges in this emerging field, and show how we push the boundary by making “2D antiferromagnets” a rising star in spintronics. I will also highlight the promises of 2D materials and heterostructures in the significant applications such as low-power spintronics and quantum computing/communication.


Dr. Cheng Gong is currently a postdoc in the Nanoscale Science and Engineering Center, University of California, Berkeley. Before moving to California in July of 2014, Dr. Cheng Gong did his Ph.D. in Materials Science and Engineering at University of Texas at Dallas, since 2008.
