Effect of organic membrane thickness on membrane properties and electrical characteristics of the MCP

In order to study the properties of the organic membrane as the substrate of the Al₂O₃ ion barrier film, the micro-micromorphology of organic membrane with different thickness was analyzed by step tester and metallographic microscope, and study the influence about the thickness of the organic membrane on the electrical characteristics of the MCP. The experimental results show that as the thickness of the organic membrane increase, the continuity and compactness of the organic membrane increase; and the loss of the current gain of the ion barrier MCP also increase. When the current gain of MCP without ion barrier film was 16000, and the thickness of organic membrane is 121nm, the current gain of the MCP with the ion barrier film was reduced by 94％.
