Development of a High-sensitivity Geiger Mode Silicon Photomultiplier

Abstract

The silicon photomultiplier (SiPM) is a semiconductor photosensor comprised of many micropixels. Acting as on independent Geiger mode counter that can count a single photon, the micropixels in the SiPM from a highly-sensitive photosensor like a photomultiplier tube (PMT). Also, the SiPM can be applied to various applications that require a fast reaction time, a low power, compactness, etc. If implemented as multi pixels of a SiPM, the photosensor can be used as an image sensor.
