Organization of Matter on Different Size Scales

Elena Shevchenko and Dmitri Talapin of the NanoBio Interfaces Group, together with Andrey Rogach, recently reviewed developments in nanocrystal superstructures since the publication of their highly cited article on this topic in 2002.

That original article focused on using nanocrystals as “modules” for functional materials by letting them self-assemble into ordered superlattices. At that time, the research community had already developed methods for synthesizing nanocrystals of several materials and demonstrated the possibility of assembling them into simple one-component superlattices. Since then, nanocrystal synthesis has seen tremendous progress. Today, most important metals, semiconductors, and magnetic materials can be synthesized in form of highly crystalline and monodisperse nanoparticles. The ability to assemble precisely engineered nano-building blocks into complex, hybrid materials with designed properties is opening the door to a new generation of complex materials. We expect that this new class of materials will be a source of rich new chemistry and physics and can make an impact in electronics, photovoltaics, thermoelectrics, and solid-state lighting.
