Fabrication‐Driven Oxidation Pathways in Y/Hf‐Modified High‐Entropy Alloys: From Elemental Segregation to Oxide Homogeneity

Rare Metals, Volume 45, Issue 2, February 2026.
ABSTRACT This study elucidates the oxidation mechanisms governing Y/Hf‐doped AlCoCrFeNiTi high‐entropy alloys (HEAs) and reveals the pivotal role of fabrication processes in dictating high‐temperature oxidation behavior. We demonstrate that casting and spark plasma sintering (SPS) promote Y/Hf segregation, resulting in heterogeneous oxide formation and

Integration of Laser‐Patterned Photonic Crystals in Si Solar Cells

Advanced Optical Materials, Volume 13, Issue 35, December 12, 2025.
Photonic crystal textures are integrated into silicon solar cells using laser‐patterned alumina masks and plasma etching. An isotropic defect‐removal process preserves surface passivation and optical quality, enabling 23.1% efficiency. This scalable process with periodically anchored masks and Bessel‐beam patterning marks an important step toward ...

Competition between gettering by implantation-induced cavities in silicon and internal gettering associated with SiO{sub 2} precipitation [PDF]

, 1996
Dissolved or metallic impurities can degrade silicon integrated circuit (IC) device yields when present in the near surface, active device region. This is such a critical issue that the IC community has set specifications for the reduction of metallic ...

Analysis of simultaneous boron and phosphorus diffusion gettering in silicon

, 2022
S.2589-2592We studied the simultaneous phosphorus and boron diffusion gettering (BDG) of iron in silicon by physical modeling. We present improvements to the previously used models for BDG and phosphorus diffusion gettering (PDG).

Bi‐Continuous W‐Rich Refractory High Entropy Alloy‐Cu Composite: Toward Material Innovation of Nuclear Reactor Coolant System

Small Methods, Volume 9, Issue 12, December 1, 2025.
This study focuses on developing a composite of the refractory high entropy alloy WTaVTi with Cu, using a liquid metal dealloying process. The resulting composite features highly thermally conductive Cu channels embedded between ligaments of RHEA, which exhibits excellent irradiation resistance.

On composition, structure and gettering in polycrystalline Si passivating contacts for solar cells by atom probe tomography

Materials Today Advances
Doped polycrystalline Si (poly-Si) contacts with a nanoscale SiOx interlayer have attracted significant interest due to their excellent surface passivation and impurity gettering properties for high-efficiency crystalline Si photovoltaics. However, there

Disordered Rocksalts as High‐Energy and Earth‐Abundant Li‐Ion Cathodes

Advanced Materials, Volume 37, Issue 46, November 20, 2025.
Disordered rocksalts with lithium excess (DRX) offer a new direction in Li‐ion cathode design beyond conventional Ni‐ and Co‐based materials. This review highlights the design principles, synthesis strategies, and performance optimization of DRX oxides and oxyfluorides for energy‐dense, sustainable batteries using Earth‐abundant transition metals and ...

Gettering in ISX-B [PDF]

, 1982
Gettering is used in the ISX-B tokamak to reduce the impurity concentration. This paper documents the gettering process used, and compares the expected changes in recycling and radiation with those observed experimentally.
