Abstract
- It has been shown that combining 2D materials in vertical or lateral heterostructures can significantly change and improve their electronic properties, making them more applicable for various purposes, e.g., nanoelectronics, spintronics, energy storage, catalysis etc. In this paper, we employ first principle calculations to investigate the influence of Li adsorption on lateral heterostructures composed of nanoribbons of graphene and hexagonal boron nitride. The results indicate the profound role of the nanoribbon interface. With respect to the sole graphene or boron nitride nanoribbons, Li atoms more strongly adsorb to their lateral interface due to the hybridization of electronic states. This leads to the severe changes in the electronic band structure. Our findings show that in the case of boron terminated zigzag nanoribbon interface, metallic character of the nanoribbon is changed upon Li adsorption. It opens an indirect bandgap of about 0.2 eV, showing that Li adsorption can be used for tuning electronic properties of the nanoribbons. [ABSTRACT FROM AUTHOR]
