- Summary:In this paper, the structural, electronic and magnetic properties of fully and partially surface modified
SiGe nanosheets (NSs) have been investigated using first-principles calculations based on density
functional theory. The results demonstrate that the electronic and magnetic properties of SiGe NSs can
be tuned by decorating H, Cl and F atoms on Si sites in SiGe NSs. It is shown that by decorating their
surface with H, F, and Cl atoms, H–SiGe, F–SiGe, and Cl–SiGe NSs in FM states are predicted to behave
as a semiconductor, half-metal, and metal, respectively. The diverse electronic and magnetic properties
define the potential applications of SiGe nanosheets in electronics and spintronics. - Co-author:W. X. Zhang,* Y. B. Wang, P. Zhao and C. He*
