Transmission electron microscopy (TEM) is a high-resolution imaging technique in which a beam of electrons passes through a thin sample to produce an image. The electron beam is impacted by the sample’s thickness/density, composition and, in some cases, ...

TEM Imaging&Analysis简称TIA,是FEI的一款透射电镜图像和能谱图处理分析软件,也是和Gatan Digital Micrograph类似的一款软件。 TIA能谱EDS点测定性分析 自动识别能峰(Peak ID) Peak ID 注意事项 如果谱简单(只有很少的峰,且峰与峰之间没有叠加),自动识别就能很好的识别各峰 谱越复杂越容易出现错误识别现象。比如,峰...
1. 明场成像(Bright Field Imaging):这是TEM中最普遍的成像方式,通过透射电子形成图像,适用于观察样品的整体形貌和晶体缺陷。2. 暗场成像(Dark Field Imaging):通过选择特定散射角度的电子进行成像,以突出样品中的特定结构。3. 高分辨透射电子显微镜(HRTEM):通过直接成像电子波的干涉图样,实现对晶体结构的...
产生了如图12所示的出色图像。图12. (a)单层和双层石墨烯片的出射波函数(EW)重建TEM图像;(b,c)单层和双层区域部分的高倍彩色图像。Jinschek, J.R.; Yucelen, E.; Calderon, H.A.; Freitag, B. Quantitative atomic 3-D imaging of single/double sheet graphene structure. Carbon 2011 ...
Tem Imaging & Analysis为图片编辑软件,不做EDX时可以不用。 八、图片的保存设置 点击Digital Micrograph 窗口中的图标1 在Save Numbered(图标2)中点击Browse(图标3)选择目录 将Next Index(图标4)中的序号改为1,点击OK。 分别点击Image Info(图标5)、Global Info(图标7)修改文件名称。
高分辨或原子分辨原子序数(Z)衬度像(high resolution or atomic resolution Z-contrast imaging)也可以叫做扫描透射电子显微镜高角环形暗场像(HAADF-STEM)这种成像技术产生的非相干高分辨像不同于相干相位衬度高分辨像,相位衬度不会随样品的厚度及电镜的焦距有很大的变化。像中的亮点总是反映真实的原子。并且点的强度...
