In article number 1900228, Husam H. Abu‐Safe and co‐workers present Au–Ag–Al nano‐alloy thin films as a candidate material for advanced photonic applications. The topography on the cover demonstrates that the overall granular appearance is normal for metallic thin films grown by thermal evaporation at room temperature. The films with no Al (bottom image) have an island‐type structure with hemispherical‐shaped tops. With increase in the films' Al content (indicated by the upward arrow), the islands coalesced and grew into larger features as seen on the surface. At high Al concentrations, the films formed continuous structure and smooth surfaces.

Au-Ag-Al纳米合金：Au-Ag-Al纳米合金薄膜作为光子应用的高级材料：XPS分析，连续波体制下的线性和非线性光学性质（晶体研究和技术6/2020）

在文章1900228中，Husam H. AbuSafe和同事提出了Au-Ag-Al纳米合金薄膜作为先进光子应用的候选材料。盖上的形貌表明，对于在室温下通过热蒸发生长的金属薄膜，总体颗粒外观是正常的。没有Al的薄膜（底部图像）具有岛型结构，顶部呈半球形。随着膜中Al含量的增加（由向上的箭头指示），这些岛聚结并生长为更大的特征，如表面所示。在高Al浓度下，膜形成连续的结构和光滑的表面。
