Two-dimensional artificial nano-hybrids and their quantum properties
When different materials are interfaced/jointed with each other, the resulted hybrid systems often manifest fascinating physical properties that do not exist in nature. Among the many artificial hybrids (sometimes addressed as meta-materials or hetero-structures), nano-hybrid made with low-dimensional materials and other functional materials is attracting tremendous attentions in recent years. In this talk, we will mainly go through a couple of examples of our recent progresses on the graphene/superconducting-islands, and the 2D materials/h-Boron-Nitride nano-hybrid systems. In the former, the superconducting behavior is successfully coupled to the gate-tunable feature of graphene, leading to a metal-superconducting quantum phase transition at the ground state. While in the later, ultra-flat and ultra-clean interface allow ballistic electronic transport, opening new path to realize the paradigm of electron optics. Our recent experimental progresses on MoS2/h-BN hetero-structures will also be discussed. We expect that artificial nano-hybrids and their quantum properties can be expanded into many research areas that are important for both fundamental studies and future applications.
Zheng Vitto Han, research professor at the Institute of Metal Research, Chinese Academy of Sciences. Dr. Han has been utilizing nanoFab together with artificial staking methods to study the interfacial coupling of low-dimensional materials such as graphene and superconducting nano-dot arrays, MoS2, and hexagonal boron nitrides (h-BN), etc. He has revealed a series of exotic physical properties of such systems, with the related works published in Sicence, Nature Physics, Nature Materials and other journals.
