Abstract

The physical mechanism of field emission from the surface of epitaxial ZrO₂/W nanoheterostructure is studied under high vacuum conditions. Results reveal an abnormally high normalized brightness and high field emission stability. This abnormal thermal field emission phenomenon can be used to produce new high intensity stationary electron sources as well as efficient thermal and electromagnetic radiation energy converters
