Ion thinning
WebIon milling machine thins samples until they are transparent to electrons by firing ions (typically argon) at the surface from an angle and sputtering material from the surface. … Web1 mrt. 2024 · The diameter of Ar + ion beams during conventional ion-thinning is relatively large and causes homogeneous heating of the sample depending on its thermal conductivity. In this study, however, focused ion beams with considerably smaller diameter were used to scan across the sample during imaging.
