报告摘要：
The physical properties of two-dimensional (2D) materials have been actively investigated in today’s condensed matter physics. In this talk, I will present some of our recent research findings surrounding the structural, optical, magnetic, spintronic, and catalytic properties of 2D materials. First, we focus on the structural control during growth of 2D materials. The systems include graphene, blue phosphorene, stanene, and transition metal dichalcogenides (TMD) nanoribbons, each associated with its own atomistic growth mechanisms. Secondly, we briefly highlight on some progresses in the property optimization of 2D materials. 1) Optics: there exists a striking linear relationship between the exciton binding energy and quasi-particle band gap of 2D materials. 2) Electronics: a kinetic pathway was proposed to grow highly ordered N-doped graphene that is a 2D metal with high carrier density. 3) Spintronics: carbon quartets properly introduced into the narrowest zigzag graphene nanoribbons can serve as definitive spin switches for the propagation of spin-polarized channels along the two edges; tungsten-based TMD zigzag nanoribbons show intrinsic half-metallicity. 4) Catalysis: graphene-covered Ni is predicted to be an effective and economical catalytic platform for hydrogen evolution reaction (HER) via confined catalysis.
