Electrostatic Stabilization of Near-Surface Quantum Sensors via Dielectric Interface Engineering
Atharva Paranjape, Kathrin Küster, Olga Shevstova +6
Control of charge-state stability in near-surface quantum defects is critical for nanoscale sensing, yet remains particularly challenging under ultra-high vacuum (UHV), where surfa…
Phase-dependent electronic structure of two-dimensional Ag layers at the graphene/SiC interface
Sawani Datta, Boyang Zheng, Arpit Jain +4
Intercalation at the graphene/SiC interface provides a controlled route to stabilize atomically thin layers with properties distinct from their bulk counterparts. In this platform,…
Charge transfer between van der Waals coupled metallic 2D layers
Bharti Matta, Philipp Rosenzweig, Craig Polley +2
Van der Waals heterostructures have become a rapidly growing field in condensed matter research, offering a platform to engineer novel quantum systems by stacking different two-dim…
Electronic Structure and Kohn-Luttinger Superconductivity of Heavily-Doped Single-Layer Graphene
Saul Herrera, Guillermo Parra-Martinez, Philipp Rosenzweig +8
The existence of superconductivity (SC) in graphene appears to be established in both twisted and non-twisted multilayers. However, whether their building block, single-layer graph…
Realization of a classical Ruddlesden Popper type bilayer nickelate in SrNiAlO with unusual Ni
Hasan Yilmaz, Kathrin Küster, Ulrich Starke +3
The discovery of 80 K superconductivity in bilayer LaNiO at pressures greater than 14 GPa presents a unique opportunity to study a novel class of high-temperature super…
Recycling of beta-Li3PS4-based all-solid-state Li-ion batteries: Interactions of electrode materials and electrolyte in a dissolution-based separation process
Kerstin Wissel, Aaron Haben, Kathrin Küster +4
All-solid-state batteries are currently developed at high pace and show a strong potential for market introduction within the next years. Though their performance has improved cons…
Phase formation in hole- and electron-doped rare-earth nickelate single crystals
P. Puphal, V. Sundaramurthy, V. Zimmermann +5
The recent discovery of superconductivity in hole-doped infinite-layer nickelates has triggered a great interest in the synthesis of novel nickelate phases, which have primarily be…
Synthesis and physical properties of LaNiO crystals
Pascal Puphal, Björn Wehinger, Jürgen Nuss +6
Infinite-layer (IL) nickelates are an emerging family of superconductors whose similarities and differences to cuprate superconductors are under intense debate. To date, the IL pha…
Momentum microscopy of Pb-intercalated graphene on SiC: charge neutrality and electronic structure of interfacial Pb
Bharti Matta, Philipp Rosenzweig, Olaf Bolkenbaas +2
Intercalation is an established technique for tailoring the electronic structure of epitaxial graphene. Moreover, it enables the synthesis of otherwise unstable two-dimensional (2D…
Probing the interlayer coupling in 2-NbS via soft x-ray angle-resolved photoemission spectroscopy
D. Huang, H. Nakamura, K. Küster +5
In the large family of two-dimensional (2D) layered materials including graphene, its honeycomb analogs, and transition-metal dichalcogenides, the interlayer coupling plays a rathe…
Electronic Structure of the Bond Disproportionated Bismuthate AgBiO
Mohamed Oudah, Minu Kim, Ksenia S. Rabinovich +11
We present a comprehensive study on the silver bismuthate AgBiO, synthesized under high-pressure high-temperature conditions, which has been the subject of recent theoretic…
Observation of a possible diluted ferromagnetism above room temperature in cobalt-substituted LaTa(O,N)3-d
