ABSTRACT:
A field emission device (100) includes an electroplated structure (122) and an electron emitter (118). Electroplated structure (122) includes a base (124), which is disposed proximate to electron emitter (118) and is made from the same material from which electron emitter (118) is made. Electroplated structure (122) further includes an electroplating electrode (126), which is disposed on base (124), and an electroplated layer (128), which is disposed on electroplating electrode (126). A method for fabricating field emission device (100) includes a step of forming electron emitter (118) and further includes a step of forming base (124) during the step of forming electron emitter (118). The method further includes a step of completely encapsulating electron emitter (118) prior to a step of forming electroplated layer (128).
