Optical lithography continues to be the popular technique for further miniaturization of electronic circuitry and its components. However, as further device miniaturization continues, complexity of pattern generation and cost increase; therefore the use of such techniques become dominantly specific to high-end applications such as microprocessor manufacturing. As an alternative, nanomaterials and non-conventional nanofabrication methods such as bottom-up chemical approaches offer great opportunities in producing useful nanostructure-based devices with potential advantages such as enhanced performance and/or lower cost. Majority of the produced nanomaterials for device applications require post processing e.g. transfer from a source- to a target substrate. For composite structures this transfer is not a concern, but for producing intricate nanodevices with a large scale hierarchical order, this step becomes a bottleneck as it requires knowledge on surface registries of a large group of nanocrystals on a given surface that is needed for the succeeding fabrication steps.
