We describe the single-step self-organization of nanocrystal superlattice films infused with spatially ordered arrays of micrometer-size pores. In a humid atmosphere, water droplets condense on the surface of evaporating thin-film solutions of nanocr

The self-assembly of sterically stabilized colloidal copper sulfide nanodisks, 14-20 nm in diameter and 5-7 nm thick, was studied. The nanodisks were observed by electron microscopy and small-angle X-ray scattering to form columnar arrays when evapor

The electrical properties of Bi2S3 nanowire bundles were investigated. The nanowires were synthesized using a solventless reaction involving a single-source bismuth thiolate precursor and stabilizing organic ligands. For electrical testing, nanowires

Orthorhombic Bi2S3 (bismuthinite) nanorods and nanowires are synthesized by the solventless thermolysis of bismuth alkylthiolate precursors. Reactions carried out in air at ∼225 °C in the presence of a capping ligand species, octanoate, produce hi

Organic monolayer-coated rhombohedral NiS (millerite) nanorods and triangular nanoprisms were synthesized using a solventless thermolytic decomposition of nickel thiolate precursors in the presence of octanoate. The size and shape distributions are r

Small-angle X-ray scattering (SAXS) was used to measure the time-dependent evolution of the size and size distribution of tetraoctylammonium-stabilized gold nanocrystals formed by arrested precipitation. The initial growth mechanism was varied by con
