Gettering of Metallic Impurities in Silicon

, 1984
We report the results of a study of the microstructural changes brought about by the gettering of metallic impurities in silicon. Phosphorus gettering proceeds by the formation of metal disilicides at the silicon/phosphosilicate glass interface.

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 ...

Effects Of Gettering On Device Characteristics

, 1996
Effective methods of gettering metallic impurities were proposed. To achieve effective gettering, an annealing process to induce gettering was modified taking fundamental gettering steps and the difference in the gettering mechanism into account.

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.

Competition Between Gettering by Implantation-Induced Cavities in Silicon and Internal Gettering Associated with SiO₂ Precipitation

, 1996
The gettering behavior of Cu and Fe was investigated in CZ silicon containing both internal-gettering sites in the bulk due to SiO2 precipitation and a device-side layer of cavities formed by He ion implantation and annealing.

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 & Precipitation Phenomena in Semiconductors

, 1984
Impurity gettering at defects/damage in Si is discussed. Details of intrinsic and extrinsic gettering in Si are presented. The utility of gettering is demonstrated by comparing the results from gettered and non-gettered test devices.

Physical mechanisms of boron diffusion gettering of iron in silicon [PDF]

, 2010
We have studied the boron diffusion gettering (BDG) of iron in single crystalline silicon. The results show that iron is gettered efficiently by electrically inactive boron, which leads to gettering efficiencies comparable to phosphorus diffusion ...

HCl gas gettering for crystalline silicon thin film solar cells

, 2022
S.001437-001440Crystalline silicon thin film (cSiTF) solar cells could be an attractive alternative for standard silicon solar cells. Only a small amount of the expensive high purity silicon is needed for the epitaxial deposition on a low-cost silicon ...
