1. A microchannel plate comprising:

  • a) a substrate defining a plurality of channels extending from a top surface of the substrate to a bottom surface of the substrate;

    b) a resistive layer comprising at least one of a nanoalloy and a nanolaminate structure formed over an outer surface of the plurality of channels, the at least one of the nanoalloy and the nanolaminate structure being chosen to have a composition that provides ohmic conduction with a predetermined resistivity that is substantially constant;

    c) an emissive layer formed over the resistive layer;

    d) a top electrode positioned on the top surface of the substrate; and

    e) a bottom electrode positioned on the bottom surface of the substrate.
