Abstract

Our high-performance time-of-flight atom probe was employed successfully in the composition analysis of zirconiated tungsten field emitters. Surface compositions were analyzed in situ under various emitter surface conditions with a mass resolution m/Δm≳2000. Our study showed that nitrogen, instead of oxygen, may play a dominant role in the surface reaction and causes the buildup of pure tungsten in the (100) plane.
