Atomic Alignment in PbS Nanocrystal Superlattices with Compact Inorganic Ligands via Reversible Oriented Attachment of Nanocrystals
Ahhyun Jeong, Aditya N. Singh, Josh Portner +12
Nanocrystals (NCs) serve as versatile building blocks for the creation of functional materials, with NC self-assembly offering opportunities to enable novel material properties. He…
Ultrafast symmetry control in photoexcited quantum dots
Burak Guzelturk, Joshua Portner, Justin Ondry +23
Symmetry control is essential for realizing unconventional properties, such as ferroelectricity, nonlinear optical responses, and complex topological order, thus it holds promise f…
Colloidal dispersions of sterically and electrostatically stabilized PbS quantum dots: the effect of stabilization mechanism on structure factors, second virial coefficients, and film-forming properties
Ahhyun Jeong, Josh Portner, Christian P. N. Tanner +7
Electrostatically stabilized nanocrystals (NCs) and, in particular, quantum dots (QDs) hold promise for forming strongly coupled superlattices due to their compact and electronical…
Origins of suppressed self-diffusion of nanoscale constituents of a complex liquid
Christian P. N. Tanner, Vivian R. K. Wall, Mumtaz Gababa +25
Understanding and ultimately controlling the transformations and properties of nanoscale systems, from proteins to synthetic nanomaterial assemblies, is limited by the inability to…
Enhancing nanoscale charged colloid crystallization near a metastable liquid binodal
Christian P. N. Tanner, Vivian R. K. Wall, Joshua Portner +17
Bottom-up assembly of nanocrystals (NCs) into ordered arrays, or superlattices (SLs), is a promising route to design materials with new functionalities, but the degree of control o…
In situ coherent X-ray scattering reveals polycrystalline structure and discrete annealing events in strongly-coupled nanocrystal superlattices
Matthew J. Hurley, Christian P. N. Tanner, Joshua Portner +13
Solution-phase bottom up self-assembly of nanocrystals into superstructures such as ordered superlattices is an attractive strategy to generate functional materials of increasing c…
In situ X-ray scattering reveals coarsening rates of superlattices self-assembled from electrostatically stabilized metal nanocrystals depend non-monotonically on driving force
Christian P. N. Tanner, James K. Utterback, Joshua Portner +7
Self-assembly of colloidal nanocrystals (NCs) into superlattices (SLs) is an appealing strategy to design hierarchically organized materials with new functionalities. Mechanistic s…
Excitonic Spin-Coherence Lifetimes in CdSe Nanoplatelets Increase Significantly with Core/Shell Morphology
Phillip I. Martin, Shobhana Panuganti, Joshua C. Portner +4
We report spin-polarized transient absorption for colloidal CdSe nanoplatelets as functions of thickness (2 to 6 monolayer thickness) and core/shell motif. Using electro-optical mo…
