Sample Preparation

TEM Sample Preparation

For transmission electron microscopy investigations, samples have to be trimmed down to a size of typically 3 milimeter in diameter and tenth or hundres of nanometer in thickness. Moreover, the sample has to withstand the vacuum condition inside the TEM.

For high resolution studies of crystalline materials, the sample needs to be prepared with respect to a certain crystallographic orientation and be thinned down to a thickness below 20 nanometer.

The center has the following equipment to do these preparations almost routinely:

If you have question on the usage of these instruments, Tom can probably help.

TEM Sample Holders

The centre has a wide range of sample holders for special studies, a lot of which were developed by the centre. Examples include
