Transport properties of InSb nanowire arrays.

Single-crystalline InSb nanowire arrays were prepared by pulsed electrochemical deposition into anodic alumina membranes, and subjected to characterization using X-ray diffraction, field emission scanning electron microscope and transmission electron microscopy. A nonlinear I–V characteristic and a decreased resistance with temperature were observed in InSb nanowire arrays. The mechanisms of the different temperature dependencies of the resistance of InSb nanowires with different diameters were discussed. [ABSTRACT FROM AUTHOR]
