Thickness‐Dependent Skyrmion Evolution in Fe3GeTe2 During Magnetization Reversal

open access: yesAdvanced Functional Materials, EarlyView.
Thickness‐ and field‐dependent magnetic domain behavior in 2D van der Waals Fe3GeTe2 is studied using Lorentz TEM and micromagnetic simulations. A patch‐like domain phase evolves from skyrmions during magnetization reversal, and step edges between thickness regions act as pinning sites.

Application of Wavelet Transform for Image Denoising of Spatially and Time Variable Astronomical Imaging Systems

open access: yesActa Polytechnica, 2011
We report on our efforts to formulate algorithms for image signal processing with the spatially and time variant Point-Spread Function (PSF) and inhomogeneous noise of real imaging systems.

Impact of Lattice Heterogeneity on Broadband Optical Retardation in Stacked 2D Perovskite Single Crystals

open access: yesAdvanced Functional Materials, EarlyView.
It is shown that interfaces between organic and inorganic layers govern long‐range stacking disorder and in‐plane anisotropy in 2D metal‐halide perovskites. By comparing single‐cation AB‐AB and ordered mixed‐cation ABCD‐ABCD stackings, SCXRD reveals enhanced mosaicity, while optics confirm high birefringence.

Heterogeneous Nanopore Arrays – Selective Modification of Nanopores Embedded in a Membrane

open access: yesAdvanced Materials, EarlyView.
Biological processes rely on the concerted action of channels with different functionalities embedded in the same membrane. Inspired by nature, heterogeneous nanopore arrays are prepared where two nanopores are connected in parallel and function as two different elements of an ionic circuit: a diode and a resistor.

Atomic‐Scale Insights into Nanoparticle Exsolution at Dislocations in Dislocation‐Engineered Catalysts

open access: yesAdvanced Materials, EarlyView.
This study reveals an atomic‐level correlation between bulk dislocations and the exsolution of surface nanoparticles through a novel approach for dislocation engineering in epitaxial thin films. Employing in situ scanning transmission electron microscopy, two primary reasons for the frequent nucleation of dislocation‐associated nanoparticles are ...
