Abstract
A composite nanoarchitecture unit is disclosed. The unit comprises a columnar film grown on top of another layer where the columns touch each other at the top forming arches having optimized characteristics. This nanoarchitecture unit, called nano-vault, achieves high mechanical stability for films under strong and variable stress action.
Claims11
A composite nanoarchitecture unit, comprising:
- a columnar film grown on top of another layer where the columns touch each other at the top forming arches having optimized characteristics.
A manufacturing method for a composite nanoarchitecture unit, the method comprising the steps of:
- a) depositing nanoparticles on substrates from the gas phase;
- and
- b) growing a columnar film on a layer of nanoparticles,
- wherein column diameters in the columnar film increased with thickness until the column tops contacted one another, closing the surface via the formation of an arched structure in the step b).
