Making STEM Specimen
We will look at each one of these methods in turn.
Making STEM Specimen – Dispersion Method
Making STEM Specimen – Microtomy Method
Making S(T)EM Specimen – Focus Ion Beam (FIB), Ion Mill, Plasma/UV Cleaner Method
Making STEM Specimen – Focus Ion Beam (FIB) Method
Making STEM Specimen – Focus Ion Beam (FIB) Method
Making STEM Specimen – Focus Ion Beam (FIB) Method
Making a Thin Cross-sectional Specimen by FIB
The FIB can weld any two pieces of material together at the nanoscale
Welding specimen to 33mm Cu grid
Limited Micro/Nano Machining
