Microchannel plate for electron multiplier

A microchannel plate for a microchannel plate electron multiplier, comprising:

• a substrate forming a plate having first and second opposing faces and having a plurality of parallel channels therethrough from first to second faces and;
• a first electrode on the first face, the first electrode having a first side adjacent to the substrate and a second side opposite to the first side;
• a second electrode on the second face, the second electrode having a first side adjacent to the substrate and a second side opposite to the first side;
• and a layer of resistive and secondary emissive material on the second side of the first electrode, configured to be deposited by atomic layer deposition and in which the layer is less than 100 nanometers thick.
