The most important differences between a transmission electron microscope and a scanning electron microscope are: Rather than the broad static beam used in TEM, the SEM beam is focused to a fine point and scans line by line over the sample surface in a rectangular raster pattern.

SEM focuses on the sample's surface and its composition whereas TEM provides the details about internal composition.

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 which are passing through the sample) to create an image. As a result, TEM offers valuable information on the inner structure of the sample, such as crystal structure, morphology and stress state information, while SEM provides information on the sample’s surface and its composition.

TEM give information about the internal structure of a sample, but can only produce a 2D image of a small area, whereas SEM is better of 3D surface morphology. ... SEM is based on scattered electrons, while TEM on transmitted.
