[Materials] High quality TEM lamella prep of InP (Indium Phosphide) using cryo-FIB

A lamella of Indium Phosphide (InP) was prepared using cryo-FIB. While FIB process at RT left sub-10 nm precipitates on the surface and consequent curtaining artifacts even after 1 kV finishing, cryo FIB process at -120 °C reduced the diameter of the In crystal precipitates. Atomic resolution HAADF-STEM image obtained at RT FIB process showed partially bright background, whereas cryo-FIB produced clear atomic columns without the influence of the precipitates.

Hi,
Please I have been trying to reach someone from the company and then I came across this video. I am using the SEM Tm 3030 for my dissertation and I want to get the thickness of film on a cellulose paper by checking the cross section. Please how do I use SEM to find cross section measurement so I can calculate the film thickness.
