摘要

摘要时间周期物理气相沉积(TP-PVD)是一种常用的平面布拉格反射镜制备方法。这些器件在理论上具有无限横向延伸和均匀性，但它们在厚度方向上具有周期性非均匀的电磁本构。在两种不同的格式下进行TP-PVD，我们发现通过在波长尺度上随机粗糙的表面上进行TP-PVD，可以避免某些薄膜应用中的Bragg现象。

On temporally periodic physical vapor deposition on random rough surfaces

Abstract. Temporally periodic physical vapor deposition (TP-PVD) is commonly used to fabricate Bragg mirrors on planar surfaces. These devices are notionally of infinite transverse extent and homogeneity, but they have periodically nonhomogeneous electromagnetic constitutions in the thickness direction. Undertaking TP-PVD in two different formats, we found that the Bragg phenomenon can be avoided in certain thin-film applications by undertaking TP-PVD on surfaces roughened randomly on the scale of the wavelength.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
