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, ...
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, crystallinity. The electrons that are tra...
BioContinuum HD 能量过滤器 先进的冷冻电镜成像过滤器——现可支持EELS和EFTEM应用 BioContinuum 能量过滤器 先进的冷冻电镜成像过滤器 —— 现在可以与 EELS 和 EFTEM 兼容使用。 EDAX Elite T EDS 系统 面向扫描透射电子显微表征 (S)TEM 和原位显微表征应用直观而易用的能量色散 X 射线谱学 (EDS) 工具。
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...
Besides high resolution for 2D images, TEM also offers 3D imaging ability which is able to explore 3D microstructure in the materials. TEM stereo microscopy can resolve simple crystal defect structure such as dislocations, stacking faults, and some precipitates with defined crystal planes; while TEM...
