Interface engineering for efficient organic optoelectronic devices using nanostructured transition metal oxides

With the advent of nanotechnology the synthesis of nanostructured materials and their useful applications have become increasingly prominent. Nanostructuring can enhance the performance of functional materials and provides them with unique properties. Exceptional qualities of nanostructured materials compared to the bulk include: (i) increased surface-to-volume ratio, which provides more surface area for both chemical and physical interactions, (ii) significantly altered surface energies that allow tuning and engineering of the materials properties, as atomic species near the surface have different bond structures than those embedded in the bulk, and (iii) quantum confinement effects, due to the inherently small size of nanostructured materials, that significantly influences, charge transport, electronic band structure and optical properties.
