Polarization-Dependent Raman Selection Rules in SbS from First Principles and Experiment
Tobias Dierke, Michael Hüttenkofer, Stefan Wolff +4
Antimony sulfide (SbS) is a semiconductor composed of quasi-one-dimensional ribbon-like structural units, which give rise to pronounced structural anisotropy in the bulk cr…
Gap-free Information Transfer in 4D-STEM via Fusion of Complementary Scattering Channels
Shengbo You, Georgios Varnavides, Sagar Khavnekar +12
Linear phase-contrast scanning transmission electron microscopy (STEM) techniques compatible with high-throughput 4D-STEM acquisition are widely used to enhance phase contrast in w…
Stacking faults from a different angle - Overcoming the edge-on limit in high-resolution defect analysis
Nicolas Karpstein, Lukas Müller, Andreas Bezold +3
The nature of stacking faults (SF) - whether intrinsic or extrinsic - plays a pivotal role in defect-mediated processes in crystalline materials. Yet, transmission electron microsc…
Correlative and in situ microscopy investigation of phase transformation, crystal growth and degradation of antimony sulfide thin films
Mingjian Wu, Maïssa K. S. Barr, Vanessa M. Koch +8
Antimony sulfide (SbS), a compound of earth-abundant elements with highly anisotropic, quasi-layered crystal structure, triggered growing interest as a solar absorber in ph…
Correlative X-ray and electron tomography for scale-bridging, quantitative analysis of complex, hierarchical particle systems
Alexander Götz, Fabian Lutter, Dennis Simon Possart +18
This study presents a comprehensive workflow for investigating particulate materials through combined 360° electron tomography (ET), nano-computed X-ray tomography (nanoCT), and mi…
Identification of Polytypism and Their Dislocations in Bilayer MoS2 Using Correlative Transmission Electron Microscopy and Raman Spectroscopy
Xin Zhou, Tobias Dierke, Mingjian Wu +7
Stacking orders and topological defects substantially influence the physical properties of 2D van der Waals (vdW) materials. However, the inherent features of 2D materials challeng…
Improving electron tomography of mesoporous silica by Ga intrusion
Alexander Kichigin, Johannes Böhmer, Moritz Buwen +11
Electron tomography (ET) offers nanoscale 3D characterization of mesoporous materials but is often limited by their low scattering contrast. Here, we introduce a gallium (Ga) intru…
Breakdown of Magic Numbers in Spherical Confinement
Junwei Wang, Jonathan Martín-González, Lukas Römling +6
Magic numbers in finite particle systems correspond to specific system sizes that allow configurations with low free energy, often exhibiting closed surface shells to maximize the…
3D Electron Diffraction -- The Missing Slice for a Complete Nanoscale Analysis of Organic Solar Cells in TEM
Irene Kraus, Mingjian Wu, Stefanie Rechberger +11
Optimizing the performance of organic solar cells (OSCs) hinges on a comprehensive understanding of their nanostructures, yet traditional characterization methods often fall short,…
Optomagnetic forces on YIG/YFeO3 microspheres levitated in chiral hollow-core photonic crystal fibre
Soumya Chakraborty, Gordon K. L. Wong, Ferdi Oda +9
We explore a magnetooptomechanical system consisting of a single magnetic microparticle optically levitated within the core of a helically twisted single-ring hollow-core photonic…
Improving reconstructions in nanotomography for homogeneous materials via mathematical optimization
Sebastian Kreuz, Benjamin Apeleo Zubiri, Silvan Englisch +5
Compressed sensing is an image reconstruction technique to achieve high-quality results from limited amount of data. In order to achieve this, it utilizes prior knowledge about the…
Fabrication and extreme micromechanics of additive metal microarchitectures
Sung-Gyu Kang, Barbara Bellon, Lalithkumar Bhaskar +14
The mechanical performance of metallic metamaterials with 3-dimensional solid frames is typically a combination of the geometrical effect ("architecture") and the characteristic si…
Forming a highly active, homogeneously alloyed AuPt co-catalyst decoration on O2 nanotubes directly during anodic growth
Haidong Bian, Nhat Truong Nguyen, JeongEun Yoo +10
Au and Pt do not form homogeneous bulk alloys as they are thermodynamically not miscible. However, we show that anodic TiO nanotubes (NTs) can in-situ be uniformly decorated wi…
