Structural stabilities and electronic properties of fully hydrogenated SiC sheet

► Structural and electronic properties of fully hydrogenated SiC sheet are studied. ► Both chair-like and boat-like configurations are dynamically stable. ► While the chair-like conformer is energetically more favored. ► The chair-like and boat-like conformers are nonmagnetic semiconductors. ► The bondings are characterized with covalency.
