The crystal structure and growth direction of nanowire arraysCu 2 S

First published as an Advance Article on the web 18th July 2001 We examine the crystal structure and growth direction of nanowire arrays grown from copper surfaces atCu2S room temperature. By using X-ray diraction (XRD), transmission electron microscopy (TEM) and electron diraction (ED) techniques, the monoclinic nanowires are shown to grow preferentially along the c-axis,Cu2S characterized by a layered structure. This result may shed light on the unusual growth mechanism of the Cu2S nanowires. I
