Description


Title: 2D Magnetism and Novel Spintronic Devices


Speaker: Dr. Cheng Gong, University of California, Berkeley

Abstract: 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 and device architectures. The recently discovered magnetic 2D van der Waals materials (hereafter abbreviated as “2D magnets”) provide ideal platforms to enable the atomically-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 unprecedented properties and functionalities. In this talk, I will speak on our experimental observation of the 2D magnetism, and show how we utilize such atomically thin magnetic flatlands to develop novel spintronic devices such as low-power magnetoresistive memories, high-efficiency spin field-effect transistors, and quantum sensors. I will also highlight the promises of 2D magnetic heterostructures in the significant applications including quantum computing/communication and energy harvesting/conversion.


Bio: Dr. Cheng Gong is a postdoc in the Nanoscale Science and Engineering Center, University of California, Berkeley. Before moving to California in 2014, Dr. Gong did his Ph.D. in Materials Science and Engineering at University of Texas at Dallas, since 2008. Dr. Gong’s sustained contribution to the scientific field of low-dimensional materials and devices, particularly including his original contribution to the 2D magnetism and spintronics, can be found in his 17 first-authored publications in high-profile journals such as Nature, Science, Nature Electronics, PNAS, Nano Letters, ACS Nano, etc.
