Abstract :
As a first assessment for the fabrication of Geiger mode avalanche photodiode arrays, the individual pixels are made. A CMOS compatible technology is used, to allow the future integration of the pixels in an array with readout electronics. A model for afterpulsing is presented that relates the afterpulsing probability to the concentration and capture cross section of the traps in the depletion layer. Also a trap assisted tunneling model is used to explain the bias voltage and temperature dependence of the dark count rate. Measured results on the fabricated devices are compared with the described theory
