Abstract
A method of fabricating a microchannel plate includes defining a plurality of pores extending from a top surface of a substrate to a bottom surface of the substrate where the plurality of pores has a resistive material on an outer surface that forms a first emissive layer. A second emissive layer is formed over the first emissive layer. The second emissive layer is chosen to achieve at least one of an increase in secondary electron emission efficiency and a decrease in gain degradation as a function of time. A top electrode is formed on the top surface of the substrate and a bottom electrode is formed on the bottom surface of the substrate.
