Abstract
Electron emission from molybdenum field emission microcathode arrays is sen sitive to the contamination of the emitters by the residual gases. We studi ed the effects of H2O exposures on the emission properties of several Spind t-type molybdenum field emitter arrays. Exposure of the field emitters to H 2O resulted in emission degradation ranging from (13.8+/-5.7)% for 50 L to 90.7% for a 4000 L exposure. (C) 1999 American Vacuum Society. [S0734-211X( 99)03502-7].
