Multi-Mode Lens for Momentum Microscopy and XPEEM: Theory
Olena Tkach, Gerd Schoenhense
The strong electric field between the sample and the extractor is the core of cathode lenses and a pivotal determinant of high resolution. Nevertheless, fields in the range of 3-8…
Orbital magnetization in the Nb-substituted Kagome metal CsVSb
H. J. Elmers, O. Tkach, Y. Lytvynenko +12
This study uses angle-resolved photoemission spectroscopy to examine the low-temperature electronic structure of Cs(VNb)Sb, demonstrating that partially s…
Time- and Polarization-Resolved Extreme Ultraviolet Momentum Microscopy
Sotirios Fragkos, Quentin Courtade, Olena Tkach +7
We report the development of an instrument combining an ultrafast, high-repetition-rate, polarization-tunable monochromatic extreme ultraviolet (XUV, 21.6 eV) beamline and a next-g…
Unveiling Fine Structure and Energy-driven Transition of Photoelectron Kikuchi Diffraction
Trung-Phuc Vo, Olena Tkach, Aki Pulkkinen +8
The intricate fine structure of Kikuchi diffraction plays a vital role in probing phase transformations and strain distributions in functional materials, particularly in electron m…
Layered Multiple Scattering Approach to Hard X-ray Photoelectron Diffraction: Theory and Application
Trung-Phuc Vo, Olena Tkach, Sylvain Tricot +10
Photoelectron diffraction (PED) is a powerful and essential experimental technique for resolving the structure of surfaces with sub-angstrom resolution. In the high energy regime,…
GeSi single crystals for Ge hole spin qubit integration
Andreas Fuhrberg, Pia M. Düring, Olena Fedchenko +9
Spin qubits are fundamental building blocks of modern quantum computing devices. The path of Ge-based hole-spin qubits has several advantages over Si-based electron-spin systems, s…
