The NanoStencil project seeks to address a key issue in nanomaterials fabrication, which is how to structure materials in all three dimensions on the true nanoscale? Our vision is of a new process philosophy for the production of dense arrays of identical nanostructures of precise dimensions based on the interaction between light patterns and surface reaction processes. In Nanostencil we apply coherent laser pulses inside a growth environment to achieve interference patterning and thereby directly modify local reaction processes, resulting in the formation of ordered sites for self-assembly. The method will be applied to the direct synthetisation of metallic, semiconducting and biological nanomaterials with diverse applications including quantum optoelectronics, sensing and medical devices. The project is led by Professor Mark Hopkinson at the University of Sheffield and has 5 project partners.
The project has been able to create dense arrays of nanostructures by performing in-situ laser interference during materials synthesis with relatively low pulse energies. The project partners have deployed this approach across several diverse materials systems using different types of reaction vessels.
