Abstract

Oxidation characteristics of Si0.85Ge0.15 nanowires were investigated using transmission electron microscopy (TEM) analyses. Si0.85Ge0.15 nanowires were grown in a tube furnace by vapor-liquid-solid (VLS) method and thermally oxidized at 925 °C for 1-8 h. After oxidation, oxide thicknesses were measured using TEM images. Si0.85Ge0.15 nanowires showed a thicker oxide than Si nanowires, for the whole range of oxidation time. The oxidation rate of Si0.85Ge0.15 nanowires significantly decreased in nanowires with diameters less than 150 nm. Long-term oxidation in Si0.85Ge0.15 nanowire resulted in the oxidation of germanium atoms.
