Nanoscale Surfaces and Interface

The research program concerns colloidal synthesis of inorganic semiconductor nanometer-sized crystallites and their use as building blocks for optoelectronic and photonic applications, via self-assembly into ordered suprastructures up to the macroscopic size scale required for useful devices. Components and functionalities can be designed and added, leading to novel properties peculiar of the resulting system that arise with increasing matter complexity. Particular emphasis is put on the surface chemistry of the colloidal nanocrystals to subtly tune the optoelectronic properties and inter-nanocrystal non-covalent bonding interactions; we ultimately pursue a thorough description towards control of the interfaces in nanocrystal-based solids over multiple length scales.
