| Abstract(in English) | We calculated the phonon-limited hole mobility of Ge nanowires with rectangular cross sections based on atomistic methods, a tight-binding approximation and a valence force field model, and investigated the impacts of the orientations and cross-sectional shapes of nanowires on the hole mobility. By analyzing the geometry dependence of mobility based on the valence band structure of Ge nanowires, we showed that the geometry dependence of mobility is understandable by an average effective mass and the density of states of holes. Among the geometries investigated in this study, [110]-oriented nanowires with larger cross-sectional height along the [001] direction showed the highest hole mobility, which indicates that such nanowires are promising as the channel material of p-MOSFETs. |
