Using DualBeam to prepare the highest quality samples for atomic scale HR-S/TEM
LaB6 emitter failure case study - LaB6 emitters are widely used in electron microscopy as high brightness electron sources, owing to their favorable properties for thermionic emission: low work function and high melting point. The emitter consists of an LaB6 single crystal with a carefully shaped tip. This study offers an unprecedented characterization of a worn-out LaB6 emitter down to the atomic level.
