Data underlying the article: Position-dependence of valley polarization and valley coherence of WS2 monolayer flakes

This is the dataset underlying the article: Position-dependence of valley polarization and valley coherence of WS2 monolayer flakes.<br>Running the matlab scripts will generate the figures in the main article and the supplementary materials. The figures display photoluminescence spectra and maps of PL intensity, valley polarization and valley coherence of different WS2 monolayer flakes. <br>

本数据集支撑以下研究论文：《单层二硫化钨（WS₂）薄片的谷极化（valley polarization）与谷相干性（valley coherence）的位置依赖性》。
运行该Matlab脚本可生成正文章节与补充材料中的全部图表。
这些图表展示了不同单层二硫化钨薄片的光致发光（Photoluminescence，简称PL）光谱、PL强度分布图、谷极化与谷相干性特征。
