Abstract
Electronic band structure and energetic stability of two
types of <110> and <001> oriented silicon nanowires in
β-Sn phase with the surface terminated by hydrogen atoms were
studied using density functional theory. It was found that
β-Sn nanowires are metastable with zero band gap against to
nanowires in diamond phase. The relative energy of the studied wires
tends to the energy of the bulk silicon crystal in β-Sn
phase.
