Zinc Oxide Nanomaterials from Zn(II) complexes
What is it about?
Zinc oxide nanostructures are increasingly important for technology. Chemical Vapor Deposition (CVD) is a widely used method to realize these materials, but the molecular details of the fabrication process are unknown. For example, there are still many open questions regarding how the precursor molecules decompose and react to form the new material when they come in contact with the growth surface. Using computer modeling, here we show how a precursor for ZnO nanostructures behaves on a support for CVD deposition.
Why is it important?
This study demonstrates the key role of the temperature of the CVD growth surface in triggering the activation of the precursor. A key result is that the zinc precursor molecules in contact with the heated surface undergo a fast rolling motion, which occurs at much lower temperatures compared to copper precursors of the same family. This finding may explain the different reactivity and the different type of oxide nanostructures obtained from chemical vapor deposition using copper and zinc precursors.
