Strategies for Controlled Assembly at the Nanoscale

The bottom–up approach is considered a potential alternative for low cost manufacturing of nanostructured materials. It is based on the concept of self–assembly of nanostructures on a substrate, and is emerging as an alternative paradigm for traditional top down fabrication used in the semiconductor industry. We demonstrate various strategies to control nanostructure assembly (both organic and inorganic) at the nanoscale. We study, in particular, multifunctional materials, namely materials that exhibit more than one functionality, and structure/property relationships in such systems, including for example: (i) control of size and optical properties of semiconductor nanostructures, synthesized by reactive laser ablation; (ii) using surface cues to steer the assembly of organic building blocks; (iii) we devised new strategies for synthesizing multifunctional nanoscale materials to be used for electronics and photovoltaics.
