| Abstract: | InSb/Sb superlattice nanowires array with diameter of 60 nm, embedded in anodic alumina membrane (AAM)template were fabricated by pulsed electrodeposition. Morphology and structure characterization of the superlattice nanowires were performed by using scanning electron microscopy (SEM), transmission electron microscopy (SEM)and energy dispersive X-ray spectrometer (EDS).The length of the highly ordered InSb/Sb superlattice nanowires was about 40 μm, and its aspect ratio was more than 600. In this experiment, the components and structure of the InSb/Sb superlattice nanowires were controlled by changing deposition voltage and time.The atomic ratio of In to Sb in the superlattice nanowires was about 1/2, and the thickness of InSb and Sb were 12 nm and 20 nm respectively in each period.The study of the nanowires growth showed that the fabrication parameters, such as temperature and voltage, had a strong influence on the growth of the InSb/Sb superlattice nanowires.And the deposition rate of Sb was higher than that of InSb in the deposition process. |
