| Abstract(in English) | We calculated the conduction band structures of [001]- and [110]-oriented Si nanowires with rectangular cross section using a tight-binding approximation and investigated the dependence of the band structures on those cross-sectional shapes. By comparing them with the full-band distribution of bulk Si, the subband structures of Si nanowires with the width over 4nm can be quantitatively explained by nonparabolicity of the conduction band of bulk Si. In addition, the effective mass of very narrow (< 3nm) [110] nanowires is decreased by a valley splitting and it depends on the cross sectional shapes of the nanowires. It is expected that n-MOSFETs with such nanowires have superior characteristics. |
