In a field emitter ( 100 ) including a substrate ( 110 ), the substrate ( 110 ) has a substantially non-conductive top substrate surface ( 112 ). A conductive cathode member ( 130 ) is disposed on the top substrate surface ( 112 ) and has a top cathode surface ( 132 ). A conductive gate member ( 120 ) is disposed on the top substrate surface ( 112 ) and is substantially coplanar with the cathode member ( 130 ). An emitter structure ( 140 ) extends away from the top cathode surface ( 132 ). The gate member ( 120 ) is spaced apart from the cathode member ( 130 ) at a distance so that when a predetermined potential is applied between the cathode member ( 130 ) and gate member ( 120 ), the emitter structure ( 140 ) will emit electrons.
