Abstract

We report optical anisotropy in laterally aligned bundles of metallic W6Te6 nanowires, grown on a-plane sapphire substrates by chemical vapor deposition. Mueller-matrix spectroscopic ellipsometry reveals strong directional dependence in absorption (dichroism) and refraction (birefringence) along and across the nanowire axis. These experimental observations are qualitatively supported by first-principles calculations and consideration of depolarization effects. Our findings establish W6Te6 as a model system for studying light–matter interactions in anisotropic metallic nanostructures and demonstrate its potential for polarization-sensitive photonic and optoelectronic applications.

横向排列的W6Te6纳米线束的光学各向异性

我们报道了通过化学气相沉积在平面蓝宝石衬底上生长的横向排列的金属W6Te6纳米线束的光学各向异性。穆勒矩阵椭圆偏振光谱显示了沿纳米线轴的吸收（二色性）和折射（双折射）有很强的方向依赖性。这些实验观察得到第一性原理计算和退极化效应的定性支持。我们的研究结果建立了W6Te6作为研究各向异性金属纳米结构中光-物质相互作用的模型系统，并展示了其在偏振敏感光子和光电子应用方面的潜力。

期刊介绍： Applied Physics Letters (APL) features concise, up-to-date reports on significant new findings in applied physics. Emphasizing rapid dissemination of key data and new physical insights, APL offers prompt publication of new experimental and theoretical papers reporting applications of physics phenomena to all branches of science, engineering, and modern technology. In addition to regular articles, the journal also publishes invited Fast Track, Perspectives, and in-depth Editorials which report on cutting-edge areas in applied physics. APL Perspectives are forward-looking invited letters which highlight recent developments or discoveries. Emphasis is placed on very recent developments, potentially disruptive technologies, open questions and possible solutions. They also include a mini-roadmap detailing where the community should direct efforts in order for the phenomena to be viable for application and the challenges associated with meeting that performance threshold. Perspectives are characterized by personal viewpoints and opinions of recognized experts in the field. Fast Track articles are invited original research articles that report results that are particularly novel and important or provide a significant advancement in an emerging field. Because of the urgency and scientific importance of the work, the peer review process is accelerated. If, during the review process, it becomes apparent that the paper does not meet the Fast Track criterion, it is returned to a normal track.
