Nucleation Time Effects on Intrinsic Gettering

open access: yes, 1984
In this study, nucleation time has been found to play an important role in the three-step (Hi-Lo-Hi) intrinsic gettering process. The longer the nucleation time, the higher the density of oxygen precipitates and oxidation induced stacking faults.

Impact of Iron Contamination on Liquid Properties and Microstructural Evolution in AlSi20

open access: yesAdvanced Engineering Materials, Volume 27, Issue 14, July 2025.
Recycled aluminum is much more energy conservative and sustainable than primary aluminum. However, the iron contamination in secondary aluminum is vastly responsible for the degradation of the material properties. Herein, it is aimed to evaluate the influence of iron contamination in hypereutectic Al–Si alloy through thermodynamic as well as ...

An Atomic‐Scale View at γ’‐Fe4N as Hydrogen Barrier Material

open access: yesAdvanced Materials Interfaces, Volume 12, Issue 13, July 14, 2025.
This study demonstrates the efficacy of γ’‐Fe4N nitride layers, formed via gas nitriding, as hydrogen permeation barriers. Advanced characterization, hydrogen permeation analysis, and DFT calculations reveal a 20 fold reduction in hydrogen diffusion at room temperature.

Ni reactions with surfaces: dependence of gettering efficiencies for Ni on crystal-growth conditions, back-side-gettering techniques, oxygen precipitates and thermal treatments

open access: yes, 2002
We have pet-formed measurements on the gettering efficiencies for Ni in different silicon wafers. Gettering efficiencies were measured of wafers grown by different crystal-growth techniques, such as Czochralski-grown (CZ) and floating zone (FZ), as well ...

Synthesis of Indium Nitride Epitaxial Layers on a Substrate of Porous Indium Phosphide [PDF]

open access: yesЖурнал нано- та електронної фізики, 2015
The paper presents a technique to obtain InN films on porous InP substrates by radical-beam gettering epitaxy. According to the results of the Auger spectroscopy, InN film thickness ranged from 100 nm to 0.5 microns depending on the etching conditions.

Impact of high-temperature processing steps on the long-term stability of charge carrier lifetime in n-type FZ-silicon

open access: yesEPJ Photovoltaics
In this work, the long-term behavior of excess charge carrier lifetime in n-type FZ-Si wafers without presence of highly doped layers is investigated during illumination at elevated temperatures.
