Ag2Se to KAg3Se2: Suppressing Order–Disorder Transitions via Reduced Dimensionality

Autor: Ruiyun Huang, Mercouri G. Kanatzidis, Alexander J. E. Rettie, Fei Han, James M. Hodges, Duck Young Chung, Antia S. Botana, Christos D. Malliakas

Publikováno v: Journal of the American Chemical Society. 140:9193-9202

We report an order–disorder phase transition in the 2D semiconductor KAg3Se2, which is a dimensionally reduced derivative of 3D Ag2Se. At ∼695 K, the room temperature β-phase (CsAg3S2 structure type, monoclinic space group C2/m) transforms to th

Synthetic Deconvolution of Interfaces and Materials Components in Hybrid Nanoparticles

Autor: Julie L. Fenton, Raymond E. Schaak, James M. Hodges

Publikováno v: Chemistry of Materials. 29:6168-6177

Interfaces between nanoscale solids can facilitate coupling between dissimilar materials, leading to emergent and synergistic properties as well as mix-and-match multifunctionality. Seeded-growth methods, whereby one material is grown directly off of

Insights into the Seeded-Growth Synthesis of Colloidal Hybrid Nanoparticles

Autor: James M. Hodges, Julie L. Fenton, Raymond E. Schaak, Jonathan D. Ackerman, Lucas T. Alameda, James R. Morse

Publikováno v: Chemistry of Materials. 29:106-119

Colloidal hybrid nanoparticles integrate two or more nanocrystal domains into a single architecture that can have properties not found in, or enhanced relative to those of, the individual components. These hybrid nanomaterials are typically construct
