扫描透射电子显微镜(STEM)是透射电子显微镜(TEM)的一种发展。近些年,伴随球差校正器的引入,STEM的空间分辨率达到了亚埃米级,已经可以实现单个原子柱成像观察。本文从STEM的发展史、仪器的构成及工作原理、成像模式、实际应用等方面,非常详实地讲解了STEM的相关知识。文末介绍了STEM的优缺点并将其与TEM、SEM的性能相比较...

很显然的啊，每种元素的存在性和它的分布位置，每个颜色代表一种元素
Energy-dispersive X-ray spectroscopy (EDX) is often performed simultaneously with high-angle annular dark-field scanning transmission electron microscopy (STEM) for nanoscale physico-chemical analysis. However, high-quality STEM-EDX tomographic imaging is still challenging due to fundamental limitations such...

We present the development of a new algorithm which combines state-of-the-art energy-dispersive x-ray (EDX) spectroscopy theory and a suitable machine learning formulation for the hyperspectral unmixing of scanning transmission electron microscope EDX spectrum images. The algorithm is based on non-neg...
