| Abstract(in English) | We fabricated Au-catalyzed GaAs nanowires on (111)Si substrate by combination method of a solid source molecular beam epitaxy (MBE) and vapor-liquid-solid (VLS). In order to investigate the MBE-VLS combination growth mechanism, we grew GaAs nanowires under the various conditions and observed their shapes by Scanning Electron Microscopy (SEM). At the beginning of the growth, the growth rate was very fast and the diameter of nanowires was constant along the growth direction. On the other hand, the growth rate became slow and the diameters were tapered for a long growth time. When the V/III ratio was high, the uniform and narrow nanowires were grown. At the low V/III ratio, however, the wide nanowires were grown. These phenomena might be due to the migration of Ga adatoms along the wire side facets. |
