Any technique which is based on the ) in crystalline materials and evaluation of the
diffraction
of high energy electrons (angular distribution
of the transmitted electrons. The diffraction
pattern represents an image of the reciprocal lattice and therefore contains information about crystal structure. This technique is also often called selected area electron diffraction
(SAED). For consistency
with other electron diffraction
techniques, however, the term THEED is recommended.
