Breakdown of thin-film emitters

View publication

Abstract

The examination of thin-film emitters in the scanning electron microscope has revealed a mechanism by which they break down. The top film is continuous when emission is first obtained from the device but microscopic punctures appear after a short period of operation and the emission becomes unstable. Eventually the device ceases to conduct as the number and size of the micropunctures increase. © 1972 The American Institute of Physics.
