Abstract
A field emission device (100) having an electron emitter (101), for emitting electrons, an extraction electrode (102) proximally disposed with respect to the electron emitter (101), an anode (103) for collecting some of any emitted electrons is formed. Anode (103) is distally disposed with respect to the electron emitter (101). A transient current source (110) is operably coupled between the electron emitter (101) and a reference potential (107). Transient current source (110) provides a transient current to the electron emitter (101) to enhance response time for emission of electrons from the electron emitter (101) of the field emission device (100). A controlling input line (111) is provided for current controlling signals to the transient current source (110) with the controlling input line (111) being operably coupled to the transient current source (110).
