ABSTRACT:
A microelectronic field emitter device comprising a substrate, a conductive pedestal on said substrate, and an edge emitter electrode on said pedestal, wherein the edge emitter electrode comprises an emitter cap layer having an edge. The invention also contemplates a current limiter for a microelectronic field emitter device, which comprises a semi-insulating material selected from the group consisting of SiO, SiO+Cr (0 to 50% wt.), SiO2+Cr (0 to 50% wt.), SiO+Nb, Al2O3 and SixOyNz sandwiched between an electron injector and a hole injector. Another aspect of the invention relates to a microelectronic field emitter device comprising a substrate, an emitter conductor on such substrate, and a current limiter stack formed on said substrate, such stack having a top and at least one edge, a resistive strap on top of the stack, extending over the edge in electrical contact with the emitter conductor; and an emitter electrode on the current limiter stack over the resistive strap.
