Abstract
A vacuum microelectronic device ( ) emits electrons ( ) from surfaces of nanotube emitters ( ). Extracting electrons from the surface of each nanotube emitter ( ) results is a small voltage variation between each emitter utilized in the device ( ). Consequently, the vacuum microelectronic device ( ) has a more controllable turn-on voltage and a consistent current density from each nanotube emitter ( ).
