GaAlAs—GaAs、InGaAs—InP光电器件的表面特性与有机钝化 [PDF]

open access: yesGuangtongxin yanjiu, 1984
本文讨论了GaAlAs-GaAs、InGaAs-InP光电器件中反向漏电大,性能不稳定的各种因素。为使器件反向电流减少和稳定可靠,必须采用表面钝化措施。比较了无机钝化和有机钝化的优缺点,指出用聚酰亚胺作为多种半导体器件表面钝化膜的优点和实用价值。

Pitting Behaviors of Passivated and Trans-Passivated 304 Stainless Steel [PDF]

open access: yes, 2020
为了进一步了解不锈钢钝化膜与过钝化膜的性质,本文对比研究了在不同电位下极化处理后304不锈钢样品的点蚀及表面膜性质,发现空白对照组样品的点蚀电位和1.1 V过钝化处理后样品的点蚀电位相近,而0.5 V钝化处理后样品的点蚀电位较高. 扫描Kelvin探针(SKP)实验结果也验证了这一现象. 扫描电子显微镜(SEM)结果显示,空白对照组样品表面只呈现一般样品抛光后形貌;0.5 V钝化处理后的样品表面被颗粒状钝化膜所覆盖,该膜层决定了样品具有较好的耐蚀性;而1.1 V过钝化处理后的样品表面出现裂缝 ...

Directed Construction of a Synergistic Li3P‐LiF Inorganic Solid Electrolyte Interphase Toward Stable Silicon Anodes

open access: yesRare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT Silicon–carbon composite anodes offer exceptionally high energy density, but their practical application is severely constrained by the structural instability and continuous evolution of the solid electrolyte interphase (SEI). In this work, moving beyond conventional LiF‐enrichment strategies, we propose a directional regulation approach based

Effect of Worm‐Like Amorphous Phase on Corrosion Resistance and Antibacterial Properties of NiTiCu Alloy

open access: yesRare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT By adding CuO, the worm‐like amorphous phase and atomic clusters were simultaneously introduced, enabling the (Ni40Ti40Cu20)99.9O0.1 alloy micron columns to exhibit a uniform flow strain of over 40% and a strength of over 2.5 GPa during compression.

Unveiling Temperature‐Dependent Corrosion Behaviors of FeNiCrMoCBY Amorphous Alloy Coatings In Spent‐Fuel Storage Environments

open access: yesRare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT A comparative study was performed to elucidate the temperature‐dependent corrosion kinetics and the semiconductor/structural characteristics of the passive film formed on Fe40Ni7Cr17Mo12C13B9Y2 (at%) amorphous alloy coatings. The results indicate that increasing temperature accelerates the corrosion kinetics of the coating.

Broad‐Spectral Response Lead Halide Perovskite Solar Cells Through Integration of Multifunctional Organic Bulk‐Heterojunction and Quantum‐Cutting Downconversion Materials

open access: yesRare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT Expanding near‐infrared (NIR) spectral response and utilizing ultraviolet (UV) photons are effective strategies for enhancing the power conversion efficiency (PCE) of lead halide perovskite solar cells (PSCs). However, the range of NIR spectral response extension and the utilization of UV light for devices are not enough, and the loss of ...

A Multifunctional Reducing Molecular Dopant for 16% Efficient Tin Perovskite Solar Cells

open access: yesRare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT Although lead‐based photovoltaics have seen remarkable progress, tin‐based perovskite solar cells (Sn‐PSCs) continue to face challenges due to their limited power conversion efficiency and insufficient operational stability. The primary cause of this performance gap is the susceptibility of Sn2+ to oxidation, which promotes rapid defect ...
