Abstract

Superlattices made fast and free The spontaneous assembly of two different types of nanoparticles into ordered superlattices can be used to design materials with precisely controlled properties. Current synthesis strategies, in which superlattices are grown on a solid substrate, have many practical limitations. A new fabrication process reported in this issue overcomes some of these, achieving rapid (minutes versus the several hours for traditional methods) formation of binary nanocrystal superlattices covering several square millimetres, large enough to be practically useful. The new method generates superlattice structures at a liquid–air interface, allowing the material to be freestanding or to be transferred to any substrate ready for fabrication into devices.
