Model for electronic properties of lattice commensurate graphene-hBN multilayers

  • Xi Chen

Student thesis: Master of Science by Research


In this thesis, we study a structure in which a graphene layer is lying on the top of an hBN layer in a commensurate manner, and is periodically stacked along the z direction. We will study three stacking configurations, and mainly focus on one of the configurations that the carbon atom is directly above the boron atom. We aim to study the electronic properties of the system based on the characteristics of the band structure using a tight-binding model, furthermore the topological properties of the most preferable carbon-boron configuration, where we find that in such configuration the bands have crossing points that act as Weyl nodes, and therefore conclude that the material is Weyl Semimetal.
