Abstract:
1. A method for making the electron emission apparatus, the method comprising: (a) providing an insulating substrate having a surface; (b) forming a plurality of grids on the insulating substrate defined by a plurality of electrodes; (c) fabricating a plurality of conductive linear structures supported by the plurality of electrodes, the plurality of conductive linear structures being substantially parallel to the surface and each of the plurality of grids contains at least one of the plurality of conductive linear structures; and (d) cutting the plurality of conductive linear structures to form a plurality of electron emitters, each of the plurality of electron emitters having two electron emission ends defining a gap therebetween; wherein in step (c), each of the plurality of conductive linear structures comprises at least one carbon nanotube wire, and the step (c) further comprises:
