Abstract

First-principles calculations based on density-functional theory reveal some unusual electronic properties of group-IV nanosheets functionalized with hydrogen and fluorine. According to difference in electronegativity between H and F atom, fully hydrogenation, full fluorination and codecorated with H and F are all break the symmetry of Dirac point and could tune the size of band gap. Fully fluorination generates the smallest band gap, while fully hydrogenation gain the biggest band gap. The diverse electronic properties of decorated group-IV nanosheets have the potential for wider applications of 2D-based materials and devices.
