It depends on what kind of material are you studying, for example bulk or powders. Determining morphology, grain size, particle size, dislocations, crystallographic data (such as plane indices) and diffraction patterns are some of the typical information which can get from TEM. Very high resolution is the most important advantage of TEM. Nowadays using high resolution TEM (HR-TEM) provide looking at atoms of materials.

@Amin Nozari I am agree with you but I just wanted to know a general aspect suppose if someone ask What feature or analysis we get from XRD we have very precise answer for it .....so like that only I want to know about its analysis part as well as potential interpretation.

Thank you

If you are most interested in "a general aspect of what features or analysis we get from TEM," I would say that TEM is especially good at identifying defects, determining phases and their orientations, and measuring chemistry on a small scale. The high resolution capabilities also allow for analysis of nano-materials and grain boundaries.

@Kenneth Towe : Thank you for so much experienced words. I am totally agreed with your view but I had raised this query not just to know the thing as it is but to make you aware that a huge part of young researcher in the developing world are devoid of this high throughput tehnology for characterization. Being part national Lab I have chance to access these thing easily but many of the people still know TEM or HR-TEM from definition only.

Very few knows about sample preparation....few gone with youtube videos etc but basic theme for powder, thin film, liquid solution etc sample for sample preparation is not very obvious.

Interpretation is another big challenge.

So I want a small glimps in this area can you enlighten us with these query.

Try wikipedia.... that will be a good start

Search for "electron microscopy basics" in google.. you will get many results..
