Resistance spikes of NiO/ZnO heterostructures in magnetic field

Frontiers in Physics
NiO/ZnO semiconductor heterostructures were fabricated via electrospinning to investigate their resistance behavior under varying magnetic fields. The resistance of the heterostructures was measured at different temperatures and in magnetic fields of ...

Room Temperature Evidence of PtTe2 Topological Semimetal Character

physica status solidi (RRL) – Rapid Research Letters, EarlyView.
We report on a melt growth process for the synthesis of high‐quality PtTe2 crystals, as assessed by X‐ray diffraction and X‐ray photoemission spectroscopy characterization. By angle‐resolved photoemission spectroscopy investigation, we observe the expected topological features at cryogenic temperature and we demonstrate their stability even at room ...

Fermi Surface Structure Revealed by Quantum Oscillations in Half‐Heusler Semimetal LuAuSn

Rare Metals, EarlyView.
ABSTRACT The Fermi surface structure in the half‐Heusler semimetallic compound LuAuSn was systematically investigated using quantum oscillation studies of high‐quality single crystals and first‐principles calculations. Clear bulk quantum oscillation signals were observed for multiple complementary physical properties, including magnetization, Hall ...

Untangling the Mechanisms in Magneto‐Electrocatalytic Oxygen Evolution

Small, EarlyView.
Magnetic fields can enhance the oxygen evolution reaction in electrocatalytic water‐splitting for green‐H2. Yet, commercialization cannot be realized until the underlying magneto‐electric mechanisms are understood. This work uses reactor orientation to untangle these mechanisms. Lorentz force is shown to control metallic plates, while spin‐polarization

System Design Considerations for Magneto‐Electrocatalysis of the Oxygen Evolution Reaction

Small, EarlyView.
Electrocatalytic water‐splitting can be controlled using a magnetic field. The commercial prospects are exciting, but the progress is stuck in the fundamental stage of research. Progress is stagnated by publications with conflicting results, incomplete analysis, and inconsistent experimental setups.

Tunable Colloidal Synthesis Enabling μ‐ARPES on Individual Bismuth Nanocrystals

Small, EarlyView.
We report a highly controlled colloidal synthesis of Bi nanosheets with tunable lateral sizes (0.6–4.1 µm), hexagonal shape, and a layered single‐crystalline structure along the {00l} planes. The nanosheets feature high phase purity and excellent ambient stability. Remarkably, O2 promotes larger lateral growth with ultra‐smooth surfaces. This scalable,

Separation of Magnetic Microparticles With Different Molecular Surface Functionalizations by Close‐to‐Surface Traveling‐Wave Magnetophoresis

Small, EarlyView.
Inducing surface‐near magnetic particle transport inside a static liquid via an engineered, dynamic potential energy landscape, different chemical surface properties of otherwise identical particles can be distinguished using simple optical observation.

Large Unsaturated Magnetoresistance in Gated MoS2 Flakes

Small, EarlyView.
Magnetotransport investigation of layered MoS2 crystals in field‐effect devices reveals strong dependence on thickness and carrier density. Monolayer MoS2 exhibits the highest magnetoresistance of 680%. A combination of density functional theory and Boltzmann transport equation simulations shows that band transport is not causing the magnetic behavior,

Universal Fabrication of Graphene/Perovskite Oxide Hybrid Heterostructures

Small Structures, EarlyView.
This study presents a universal, catalyst‐free method for the direct growth of monolayer graphene on perovskite oxides without the need for transfer. The process yielded uniform graphene formation across different insulating substrates under identical conditions, revealing a substrate‐independent growth mechanism.
