Abstract. Glass microemitters with internal carbon nanotubes show a switch-on emission current in the range of (1 to 20 μA) and stable saturation current. Nanocly TM NC 7000 Thin Multiwall Carbon Nanotubes with a high aspect ratio (>150) were used in this study. Measurements were made under ultra-high vacuum conditions at a base pressure of 10–9 mbar. Fowler-Nordheim plots of the current-voltage characteristics are shown, and current switch-on phenomena are noted.
