I have these oxide/metal/oxide sandwich samples that the thickness of it reaches below 100 nm in the areas indicated in the picture. Those are oxide/oxide regions. I am just concerned about structural studies in the aforementioned areas. The thickness of normal areas of the sandwich is around 5 micrometers. The question is:
1. Can I take it directly in the TEM sampler and just search for those areas without any sample preparation?
If not, what kind of sample preparation do you suggest(not expensive methods like Ion milling and FIB?
Dear Mehdi
From attached picture the boundary between Oxide/Metal/Oxide is not clear, so it's very difficult to analyze. Therefore, I suggest to repeat this test again and get a good image.image.
looking at scales, it sounds rather difficult to indicate the sandwich as 0.5mm x 0.5mm TEM image hiding somewhere a 0.0001 mm junction. I may try again,

This is a SEM picture of the aforementioned sample. I just want to know if it is possible to get a TEM image of this sample.

The Oxide/Oxide region forms at the edge of the sandwiches too. Would it be possible to take the sample under TEM if I just Cut a 0.5mm x 0.5mm part of it?
