Abstract

Photo detectors are configured by photocathode and electron multiplier like the Photomultiplier Tube. But the quantum efficiency of the photocathode is low as approximately 20-30%. Then we make a suggestion the new structure back irradiation photocathode. The photocathode is combined the photodiode and the field emitter. The quantum efficiency of the photodiode is approximately 100%.The device which applies the SOS substrate has high quantum efficiency of 70%. We fabricate the device which uses the bulk Si substrate for more high performance and application to image sensor.
