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 ...

Effect of the Phosphorus Gettering on Si Heterojunction Solar Cells

International Journal of Photoenergy, 2012
To improve the efficiency of crystalline silicon solar cells, should be collected the excess carrier as much as possible. Therefore, minimizing the recombination both at the bulk and surface regions is important.

Growth studies on Si0.8Ge0.2 channel two-dimensional hole gases [PDF]

, 1992
We report a study of the influences of MBE conditions on the low-temperature mobilities of Si/Si0.8Ge0.2 2DHG structures. A significant dependence of 2DHG mobility on growth temperature is observed with the maximum mobility of 3640 cm2 V−1 s−1 at 5.4 K ...

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 ...
