Orientation Mapping via Dictionary Indexing of AC-STEM Kikuchi patterns using Open-source Software
Shamail Ahmed, Johannes Haust, Felix Gruber +5
The properties of polycrystalline materials are strongly influenced by the spatial arrangement and orientations of individual grains within the microstructure, making nanoscale cha…
Sequential tilting 4D-STEM for improved momentum-resolved STEM field mapping
Christoph Flathmann, Ulrich Ross, Jürgen Belz +4
Momentum-resolved scanning transmission electron microscopy (MRSTEM) is a powerful phase-contrast technique that can map lateral magnetic and electric fields ranging from the micro…
A Small Step for Epitaxy, a Large Step Towards Twist Angle Control in 2D Heterostructures
Oliver Maßmeyer, Jürgen Belz, Badrosadat Ojaghi Dogahe +9
Two-dimensional (2D) materials have received a lot of interest over the past decade. Especially van der Waals (vdW) 2D materials, such as transition metal dichalcogenides (TMDCs),…
Structure Determination in a new Type of Amorphous Molecular Solids with Different Nonlinear Optical Properties: A Comparative Structural Analysis
Jonathan Link Vasco, Jens Ruediger Stellhorn, Benjamin Danilo Klee +10
The microscopic structure of two amorphous materials with extreme nonlinear optical properties has been studied. One of these materials exhibits second harmonic generation, while a…
Measuring spatially-resolved potential drops at semiconductor hetero-interfaces using 4D-STEM
Varun Shankar Chejarla, Shamail Ahmed, Jürgen Belz +3
Characterizing long-range electric fields and built-in potentials in functional materials at nano- to micrometer scales is of supreme importance for optimizing devices. E.g., the f…
Ultra-Broadband Visible and Infrared Light Generation Driven by Far Infrared Light in the Broad Region from 8μm to 240μm
Nils W. Rosemann, Robin C. Döring, Eike Dornsiepen +12
The most commonly used nonlinear optical process is the conversion of infrared light at 1064nm to green light at 532nm, as performed in common laser pointers. However, more relevan…
Adamantanes as white-light emitters: Controlling arrangement and functionality by external Coulomb forces
Jürgen Belz, Johannes Haust, Marius J. Müller +10
Functionalized adamantane molecular cluster materials show highly transient nonlinear optical properties of currently unclear structural origin. Several interaction mechanisms in c…
White-light generating molecular materials: correlation between the amorphous/crystalline structure and nonlinear optical properties
Johannes Haust, Jürgen Belz, Marius Müller +11
Amorphous materials are integral part of todays technology, they commonly are performant and versatile in integration. Consequently, future applications increasingly aim to harvest…
