The Indigo® zinc oxide (ZnO) nanowire structure model is 800mm long by 80mm wide & includes 208 atoms & 325 bonds. Check the parts list below for extra atoms & bonds if you want to augment this model.
Note: There are no explicit instructions on how to build this model but the basic subunit is shown in the lower right of the image.
Note: Due to limited supply of red atoms, this model currently is provided with grey and purple atoms .
Suggested Classroom Activity: Build a 3D ZnO nanowire using this kit to demonstrate the anisotropic c-axis growth of the wurtzite lattice.

The image shows a simplified version of a zinc oxide (ZnO) "nanowire" model. We built it with only 3 subunits across to keep the cross section small without sacrificing strength. The model is 80mm across and 800mm long & uses 15mm bonds to get the highest aspect ratio.
There are no printed instructions for this model but we prepared starter versions showing one and two layers. The main thing to watch for is that no 2 atoms of the same color are adjacent & if you look down the "tube" you see 3 distinct channels.
