Growth of superconducting boron doped diamond on 4inch silicon wafers

This study demonstrates the successful growth of superconducting boron-doped diamond films on 4-inch silicon wafers via microwave plasma chemical vapour deposition, achieving a maximum critical temperature of 4.03 K while revealing that larger wafer sizes require significantly higher gas-phase boron concentrations due to reduced incorporation efficiency and exhibit radial non-uniformity in superconducting properties.

Effect of Near-surface Thermal Spikes on Radiation Hardness of Gallium Oxide

This study reveals that while Gallium Oxide is typically radiation-hard due to its resistance to amorphization, sufficiently dense thermal spikes near the surface can induce local non-stoichiometry that suppresses recrystallization and promotes surface amorphization, offering a pathway to tailor irradiation conditions for specific applications.

The Case Against Hall-Petch Hardening in High Entropy Carbide Ceramics

This study demonstrates that fully dense, single-phase (Cr,Mo,Ta,V,W)C high entropy carbide ceramics do not exhibit a systematic Hall-Petch relationship between hardness and grain size, indicating that their mechanical response is governed primarily by indentation load and the local rock salt matrix rather than grain-boundary interactions.

Twin Domains in Van der Waals Quaternary Oxides

This study reports the discovery of naturally occurring, stable twin domains in van der Waals quaternary oxides (MTeMoO6_6) that exhibit nearly opposite birefringence across their interfaces, a phenomenon confirmed by multiple microscopy techniques and proposed to enable new applications in birefringent waveguiding, polariton steering, and frequency conversion.

Spatiotemporal programming via asymmetric dielectric engineering for nonvolatile 2D optoelectronics

This paper presents a spatiotemporal programming strategy using an asymmetric dielectric stack in a dual-floating-gate architecture to enable single-gate-controlled, nonvolatile, and reversible switching between p-n and n-p junction polarities in ambipolar 2D semiconductors, thereby facilitating high-density, multifunctional intelligent hardware.

How Accurately Can We Describe Spin Crossover?

This paper proposes a protocol to systematically determine spin-crossover energies by reverse-engineering experimental transition temperatures through the calibration of the range separation parameter in hybrid density functionals, while also quantifying associated uncertainties and validating results with high-level coupled cluster calculations.

High-Temperature Hydrogen Sensors Based on Gallium Oxide Heterojunction Diodes

This study evaluates the long-term high-temperature stability of Ga2O3-based hydrogen sensors using Pt Schottky and Cr2O3/Ga2O3 p-n diodes, identifying specific degradation mechanisms like dopant migration and grain growth while demonstrating that nitrogen-doped architectures offer a stable, albeit lower-performance, alternative to magnesium-doped designs.

An Open-Source Hardware and Software Toolkit to Enable Agentic RHEED-Guided Thin-Film Synthesis

This paper presents an open-source hardware and software toolkit that enables autonomous, AI-driven control and quantitative analysis of Reflection High-Energy Electron Diffraction (RHEED) for thin-film synthesis, thereby overcoming traditional operator dependencies and establishing a foundation for fully agentic material growth.
