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 emergent materials at reduced dimensions. The recently discovered magnetic 2D van der Waals materials provide ideal platforms to enable the atomic-thin, flexible, lightweight magneto-optical and magnetoelectric devices. Though many have hoped that the ultra-thinness of 2D magnets should allow an efficient control of magnetism, the state-of-the-art has not achieved notable breakthroughs to this end. In this talk, I will speak on our experimental discovery of the first 2D ferromagnet, and discuss our updated progress on electrical and optical control of 2D magnetism. The efficient electrical and optical control of 2D magnets have broad impacts toward NASA-concerned sensor technologies such as lightning early prediction and atmospheric aerosol detection.

Dr. Cheng Gong

Assistant Professor, Department of Electrical and Computer Engineering, Quantum Technology Center (QTC), University of Maryland (UMD).

Dr. Cheng Gong is a recipient of IUPAP Young Scientist Prize in Semiconductor Physics 2020. His research group focuses on magnetic, electronic and optical properties of 2D materials, heterostructures and nanodevices. From 2014 to 2019, he was a postdoctoral fellow at University of California, Berkeley, where he pioneered the discovery of the first magnetic 2D material and innovated the development of spintronic devices based on magnetic 2D materials. He received Ph.D. in 2013 in Materials Science and Engineering at the University of Texas at Dallas. Dr. Gong’s sustained contribution to the field can be found in his 18 first-authored publications in high-profile journals such as Nature, Science, Nature Electronics, Nature Communications, PNAS, Nano Letters, etc.
