In situ X-ray scattering reveals coarsening rates of superlattices self-assembled from electrostatically stabilized metal nanocrystals depend non-monotonically on driving force

Posted by klaurent Berkeley

Kavli Affiliate: Naomi S. Ginsberg | First 5 Authors: Christian P. N. Tanner, James K. Utterback, Joshua Portner, Igor Coropceanu, Avishek Das | Summary: Self-assembly of colloidal nanocrystals (NCs) into superlattices (SLs) is an appealing strategy to design hierarchically organized materials with new functionalities. Mechanistic studies are still needed to uncover the design principles for […]
