Abstract :
We have fabricated novel supper-induced graphite nanoneedle field emitters and Si electron- transparent films for application to electron-beam- pumped light sources. The field emitters exhibited a stable electron emission of 10 muA at an average field of 6V/ mum. The 1.5-mum-thick Si electron-transparent film with an aperture ratio of 75% achieved an electron transmittance of about 60% at an acceleration voltage of 27kV. We have also demonstrated an electron-beam- pumped light source realized by the excitation of Ar gas.
