In general, if you need to look at a relatively large area and only need surface details, SEM is ideal. If you need internal details of small samples at near-atomic resolution, TEM will be necessary.Jan 11, 2019
Does TEM or SEM have better resolution?
TEM has much higher resolution than SEM. SEM allows for large amount of sample to be analysed at a time whereas with TEM only small amount of sample can be analysed at a time.May 24, 2013
Why is a SEM better than a TEM?
While SEM cannot see features to the same level of detail as TEM, it is much faster, less restrictive, and can sometimes be performed with limited or no sample preparation.Jan 11, 2019
What are the differences between TEM and SEM?
The main difference between SEM and TEM is that SEM creates an image by detecting reflected or knocked-off electrons, while TEM uses transmitted electrons (electrons that are passing through the sample) to create an image.
