Field Emission Scanning Electron Microscopy (FE-SEM) is a microscopy technique that offers approximately ten times higher resolution than conventional scanning electron microscopes (SEM). FE-SEM enables sub-nanometer resolution (theoretically up to 0.4 nm) by using a field emission gun (FEG), and its usage rate in nanotechnology has increased by 50% in recent years. This technology plays a critical role in the detailed examination of nanostructures in materials science, electronics, and biomedic
