Any technique in which an electron transparent sample is bombarded with an electron beam and the intensity of the transmitted electrons which is determined by @[email protected] phenomena (electron absorption phenomena) in the interior of the sample is recorded. TEM essentially provides a high resolution image of the microstructure of a thin sample. This technique is often just called @[email protected] The term @[email protected] @[email protected] is however recommended for the sake of a clear distinction from other electron microscopic techniques.
