Displacement of Atoms due to Electron Irradiation in EMs

With high-brightness electron sources and aberration correctors, very large current density (> 106 A/cm2) in electron microscopes (EMs), especially in TEMs, can be obtained within a small electron probe in diameter (< 1 nm), resulting in displacement damage in stationary analysis or scanning over a limited area.
