Outline of Final Research Achievements

Ultraviolet (UV) photo-detectors are attractive for a next-generation optical disk system, fire detection,
medical positron emission tomography (PET) today. Now, photomultiplier tubes (PMTs) are used in a low level light detection for medical applications. But, they have severe problems (e.g. large device, fragile, expensive). If avalanche photodiodes (APDs) substitute PMTs, the problems above can be solved and device integration can be achieved. In this study, we have developed ZnSe-based UV-APDs with organic-inorganic structure, and demonstrated a low dark current in the same order of inorganic monolithic APDs. We have also developed integrated APDs without device separation processes.
