SEM image is geometrically equivalent to a projection obtained by extending the beam vector to intersect a plane perpendicular to the optic axis of the instrument. Projection Distortion: Image Foreshortening • When the planar specimen is tilted around an axis parallel to the image horizontal, the projection situation changes Anisotropic surface defects observed in the SEM micrographs require support for qualitative and quantitative interpretation.

A scanning transmission electron microscope (STEM) is a type of transmission electron microscope (TEM). Pronunciation is [stɛm] or [ɛsti:i:ɛm]. As with a conventional transmission electron microscope (CTEM), images are formed by electrons passing through a sufficiently thin specimen. However, unlike CTEM, in STEM the electron beam is focused to a fine spot (with the typical spot size 0.05. The secondary electron image resolution for an ideal sample is about 3.5 nm for a tungsten-filament electron source SEM or 1.5 nm for field emission SEM.
