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