Magnetism in van der Waals Heterostructure
Speaker Dr. Yingying Wu, University of California
Date 7 April 2021 (Wednesday)
Time 10:30 - 12:00
Venue Online (Zoom)

Two-dimensional (2D) spintronics now emerges as a new field as a result of the recent discovery of 2D van der Waals (vdW) magnets, which excitingly extends the synergy between spintronics and 2D materials. The goal is to achieve ‘the best of both worlds’ through exploration and exploitation of spin functionality in 2D materials. One advantage of 2D spintronics over conventional spintronics is to push the devices to the 2D limit with an effective electric control and mechanical flexibility. Furthermore, more unusual physics can be unlocked through interfacial engineering in vdW heterostructures. Stacking ultrathin vdW materials in a heterostructure provides a route of controlling, manipulating and tailoring the properties of the materials, and enabling the fabrication of designer quantum devices. Motivated by their unusual physical properties, we will talk about the interface-induced magnetic phenomena, including interface magnetic proximity and topological skyrmions. We also discuss other rich physics in magnetic vdW heterostructures and potential quantum devices based on them.


Dr. Yingying Wu is currently a postdoctoral scholar in Professor Kang Wang’s group at the University of California, Los Angeles. She received her PhD in Electrical and Computer Engineering from University of California, Los Angeles in 2020. She obtained a master in Physics from the Hong Kong University of Science and Technology in 2016 and a bachelor in Physics from Nanjing University in 2014. Her research interest includes Quantum Devices, Spintronics and Magnetism, Superconductivity and Nanoelectronics.
