scanning transmission electron microscope

[′skan·iŋ tranz′mish·ən i′lek‚trän ′mī·krə‚skōp]
(electronics)
A type of electron microscope which scans with an extremely narrow beam that is transmitted through the sample; the detection apparatus produces an image whose brightness depends on atomic number of the sample. Abbreviated STEM.
