FE-TEM / STEM

 

Images atomic and nano-scale features, measures electron diffraction and via EDS/EELS measures elemental composition of points, lines and maps in areas as small as 1-2 nm

TEM  Cartoon & Nutshell

 

FE-TEM uses electrons that travel through an extremely thin sample to image that sample.  The images have very high spatial resolution on the order of a few Angstroms.

Crystallographic features may be observed within these very thin layers.  Our systems are fitted with EDS and EELS systems that allow elemental information to be gleaned from materials with low atomic numbers and high atomic numbers (Z).

Global uses of FE-TEM/STEM include materials developmentproblem solvingfailure analysisreverse engineering, and IP verification.
