This book (Practical Electron Microscopy and Database) is a reference for TEM and SEM students, operators, engineers, technicians, managers, and researchers.

 

=================================================================================

The advantages of FIB-TEM sample preparation include site specificity at the sub-micrometer scale and homogeneous thinning of the samples consisting of multi-layers of different phases or containing two-phase interfaces.

Except that basic requirements of TEM specimen need to be paid attention to, additional requirements in FIB-TEM sample preparation are:

       i) Minimize the amorphised layers on the two surfaces of the specimen,
       ii) Minimize the surface contamination and damage caused by the Ga+ beam [1],
       iii) Avoid bending of the thin foil [2],
       iv) The specimen is thick enough so that the unaffected materials can still represent the bulk material which is studied.
