Defect migration in supercrystalline nanocomposites
Dmitry Lapkin, Cong Yan, Emre Gürsoy +18
Supercrystalline nanocomposites (SCNCs) are nanostructured hybrid materials with unique emergent functional properties. Given their periodically arranged building blocks, they also…
Resolving the pressure induced 'self-insertion' in skutterudite CoSb3
Bihan Wang, Anna Pakhomova, Saiana Khandarkhaeva +13
CoSb3, a skutterudite compound, is key in studying thermoelectric materials. Under compression, it undergoes a 'self-insertion' isostructural transition, redistributing large Sb at…
Revealing the impact of polystyrene-functionalization of Au octahedral nanocrystals of different sizes on formation and structure of mesocrystals
Dmitry Lapkin, Shweta Singh, Felizitas Kirner +11
The self-assembly of anisotropic nanocrystals (stabilized by organic capping molecules) with pre-selected composition, size, and shape allows for the creation of nanostructured mat…
Impact of the Ligand Shell on Structural Changes and Decomposition of All-Inorganic Mixed-Halide Perovskite (CsPbX3) Nanocrystals under X-Ray Illumination
Jan Wahl, Philipp Haizmann, Christopher Kirsch +9
We show that the decomposition of caesium lead halide perovskite nanocrystals under continuous X-ray illumination depends on the surface ligand. For oleic acid/oleylamine, we obser…
Spatially resolved fluorescence of caesium lead halide perovskite supercrystals reveals quasi-atomic behavior of nanocrystals
Dmitry Lapkin, Christopher Kirsch, Jonas Hiller +16
We correlate spatially resolved fluorescence (-lifetime) measurements with X-ray nanodiffraction to reveal surface defects in supercrystals of self-assembled caesium lead halide pe…
Structure-transport correlation reveals anisotropic charge transport in coupled PbS nanocrystal superlattices
Andre Maier, Dmitry Lapkin, Nastasia Mukharamova +14
Semiconductive nanocrystals (NCs) can be self-assembled into ordered superlattices (SLs) to create artificial solids with emerging collective properties. Computational studies have…
