Point defects in InGaN/GaN QWs CL dataset

Dataset of hyperspectral cathodoluminescence (CL) maps accompanying the following publication: T. F. K. Weatherley, W. Liu, V. Osokin, D. T. L. Alexander, R. A. Taylor, J.-F. Carlin, R. Butté, and N. Grandjean, “Imaging nonradiative point defects buried in quantum wells using cathodoluminescence”, Nano Letters 21, 5217-5224 (2021). Hyperspectral data is stored in the "hspy" HyperSpy HDF5 specification, and can be loaded and analysed using Python (see HyperSpy documentation). Each hspy file contains comprehensive measurement metadata accessible in the "original_metadata" attribute in Python. See the README file for more detail.

本数据集为配套以下学术论文的高光谱阴极射线致发光（hyperspectral cathodoluminescence, CL）图谱集：作者为T. F. K. Weatherley、W. Liu、V. Osokin、D. T. L. Alexander、R. A. Taylor、J.-F. Carlin、R. Butté 与 N. Grandjean，论文标题为《利用阴极射线致发光技术对量子阱中掩埋的非辐射点缺陷进行成像》，发表于《纳米快报》（Nano Letters）2021年第21卷，第5217至5224页。高光谱数据采用遵循HyperSpy HDF5规范的"hspy"格式存储，可通过Python加载并分析，具体操作可参考HyperSpy官方文档。每个hspy格式文件均包含完整的测量元数据，相关元数据可在Python的"original_metadata"属性中获取。更多细节请参阅数据集附带的README文件。
