Abstract
Field-induced electron emission from silver cathodes coated with Langmuir-Blodgett (LB) films has been studied for range of film thicknesses. This organic-film-coated cathode structure is analogous to previously studied metal-insulator-metal (MIM) structures but without the possible complication of film damage due deposition of the top electrode. The results are discussed with reference to these previous MIM studies and in comparison with the results from other cathode-coated structures showing enhanced electron emission. The qualitative features of the electron emission suggest the formation of persistent conducting filaments, while energy analysis of the emission shows both inelastic and hot-electron features.
