Abstract: Two-dimensional systems have no bulk but free surfaces, which can be further interfaced/jointed with each other. The resulted hybrid systems often manifest fascinating physical properties that do not exist in nature. In this talk, we will go through our previous works on quantum properties of the 2D materials/h-Boron-Nitride nano-hybrid systems,[1-4] such as the gate tunable polarity in a tunnel-contacted few-layered MoS2 diode,[1] van der Waals ferromagnetic nano devices,[2-3] and the 2D giant anisotropic resistance effect in few-layered GaTe.[4] At last, will briefly introduce our most recent results using a two-dimensional semiconductor to push the FinFET width to sub-nm limit.[5] 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.
