Abstract: Quantum materials host exotic states of matter with unique macroscopic phenomena, ranging from various correlated electron states to topological orders. The ability to create and manipulate their emergent properties with nanoscale precision is at the forefront of condensed matter research and underlies the future progress of new electronic and photonic technologies. In particular, 2D van der Waals (vdW) materials combined with complex transition-metal oxides exhibiting strong electron correlations open up exciting opportunities for designing new functional properties at their interface. In this talk, I will discuss a robust strategy to design novel photonic device platforms by integrating oxides into 2D materials using the notion of oxidation-activated charge transfer. Taking graphene as a model 2D system, I will describe applications of this strategy in controlling the propagation of polaritons—hybrid light-matter excitations with extreme light confinement—and in implementing low-loss nanostructured optical elements. I will further discuss future prospects of 2D/oxide heterostructures in creating new interfacial phenomena with potential next-generation device applications.
Bio: Dr. Brian Kim recently joined the Department of Materials Science and Engineering at the University of Arizona as an Assistant Professor. He received B.S. in Electrical Engineering from Northwestern University. He went onto receive M.S. and Ph.D. in Electrical Engineering from Stanford University where he worked with Prof. Harold Hwang on complex oxide heterostructures and devices. He was then a post-doctoral researcher at Columbia University working with Prof. James Hone and Prof. Dmitri Basov on 2D materials and near-field nano-optics. His research group focuses on designing low-dimensional quantum materials and heterostructures for a new generation of electronic, photonic and quantum technologies. In his free time, Brian enjoys playing guitar and watching baseball.
