The two main types of electron microscopes are the transmission electron microscope (TEM) and the scanning electron microscope (SEM). Here, we briefly describe their similarities and differences. The difference between SEM and TEM The main difference between SEM and TEM is that SEM creates...
在常规实验中,我们用到的方法有 X射线衍射分析,扫描电子显微镜分析( SEM ),透射电子显微镜分析( TEM ), BET 法比表面积分析,振动样品磁强计( VSM )磁矩分析等。 [1-3]高温合金是一种广泛用于航空航天、能源、化工、船等领域的一类金属材料,具有显著的耐高温特性和高合金化程度,又被称为“超合金”。高温合金...

The estimated sizes of 50 and 700 nm, respectively, are they estimated from TEM and SEM images?
Transmission (TEM) vs. Scanning (SEM) Electron Microscopes: What’s the Difference? Electron microscopy (EM) allows us to observe a world exponentially smaller than the one we can see with our unaided eyes or even with the familiar light microscope. Electron microscopy uses electrons to “see...
Finally, we can look at software. You may think that the only difference between SEM-EDS and TEM-EDS in AZtec is which button you click on in the selection box. This is an easy assumption to make, as you will have the same options in both modes, point & id, linescan, mapping. The...

The specimen must be prepared by making extremely thin slices to ensure that electrons are able to pass through and be scattered by the specimen. This emerging beam is detected. This technique offers the same high resolution as TEM, the difference being the timing of the beam focusing, which ...
