Chemical methods developed over the past two decades enable preparation of colloidal
nanocrystals with uniform size and shape. These Brownian objects readily order into …

BACKGROUND Interactions between inorganic nanoparticles (NPs) are central to a wide
spectrum of physical, chemical, and biological phenomena. An understanding of these …

Two major aspects of functional colloidal nanoparticles are their colloidal stability
(dispersion) and controlled assembly of nanoparticles into ordered structures. Simplifying …

Achieving ordered arrays of nanoparticles (NPs) with controlled packing symmetry and
interparticle spacing is of great importance to design complex metamaterials. Herein, we …

Colloidal superlattices are fascinating materials made of ordered nanocrystals, yet they are
rarely called “atomically precise”. That is unsurprising, given how challenging it is to quantify …

This paper addresses the assembly of body centered-cubic (bcc) superlattices of organic
ligand-coated nanocrystals. First, examples of bcc superlattices of dodecanethiol-capped Au …

Perovskite nanocrystal superlattices are being actively studied after reports have emerged
on collective excitonic properties at cryogenic temperatures, where energetic disorder is …

Nanocrystal interactions in solvent influence colloidal stability and dictate self-assembly
outcomes. Small-angle X-ray scattering is used to study how dilute oleate-capped In2O3 …

Superlattices of nanoparticles coated by alkyl-chain ligands are usually prepared from a
stable solution by evaporation, therefore the pathway of superlattice self-assembly critically …

Nanocrystal superlattices are typically fabricated by either solvent evaporation or
destabilization methods that require long time periods to generate highly ordered structures …
