Abstract
- We report on the fabrication and operation of integrated field emission cathodes containing single tungsten (W) nanofibers selectively grown by nanoscale electron beam induced deposition (EBID). A nonorganometallic precursor, WF6, was used to deposit metallic W fibers. Vacuum electrical testing reveals electrons were successfully extracted from the W nanofiber tip and were collected by a phosphor anode. Direct current versus voltage (I–V) curves exhibited Fowler–Nordheim behavior, indicating the occurrence of cold field emission. Electrical testing of these devices indicated that EBID direct-write is a promising technique for direct production or repair of field emission cathodes. [ABSTRACT FROM AUTHOR]
