CdSe Nanotube Arrays on ITO via Aligned ZnO Nanorods Templating

Using a ZnO nanorod array as the template, vertically aligned CdSe nanotubes have been demonstrated on indium tin oxide (ITO) glass in large scale. The wall thickness of the nanotube is tunable and can be increased until the formation of a continuous porous CdSe network. Detailed morphological and s...

Summary:Using a ZnO nanorod array as the template, vertically aligned CdSe nanotubes have been demonstrated on indium tin oxide (ITO) glass in large scale. The wall thickness of the nanotube is tunable and can be increased until the formation of a continuous porous CdSe network. Detailed morphological and structural characterizations of the samples during the nanotube array formation reveal a growth mechanism that can be generally applied to a wide range of materials. In particular, we found that preferable CdSe nucleation and growth on the side surface ({101̅0} planes) of the ZnO nanorods in the array is critical to the later formation of a tubular structure with controllable wall thickness.
