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…
Infrared-induced ultrafast melting of nanostructured platinum films probed by an X-ray free-electron laser
Luca Gelisio, Young Yong Kim, Seon Woo Lim +10
Understanding melting in metals is a hot topic of present research. This may be accomplished by pumping the system with infrared (IR) laser radiation, and probing it with hard X-ra…
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…
Structural Study of a Self-Assembled Gold Mesocrystal Grain by Coherent X-ray Diffraction Imaging
J. Carnis, F. Kirner, D. Lapkin +15
Mesocrystals are nanostructured materials consisting of individual nanocrystals having a preferred crystallographic orientation. On mesoscopic length scales, the properties of meso…
Gas-induced segregation in Pt-Rh alloy nanoparticles observed by in-situ Bragg coherent diffraction imaging
Tomoya Kawaguchi, Thomas F. Keller, Henning Runge +11
Bimetallic catalysts can undergo segregation or redistribution of the metals driven by oxidizing and reducing environments. Bragg coherent diffraction imaging (BCDI) was used to re…
Revealing Grain Boundaries and Defect Formation in Nanocrystal Superlattices by Nanodiffraction
Nastasia Mukharamova, Dmitry Lapkin, Ivan A. Zaluzhnyy +8
X-ray nanodiffraction is applied to study the formation and correlation of domain boundaries in mesocrystalline superlattices of PbS nanocrystals with face-centered cubic structure…
