“…In conclusion, it should be noted that during transition from the proportional * to the Geiger mode (ΔV = V b ̶ V br → 0), the Si PM gain abruptly increases and reaches ~ 10 4 , but is not equal to zero, as it is assumed in the method for determining V br proposed in Refs. [1,4,5,7,8,10] and others.…”

“…There are several methods for determining the breakdown voltage of the SiPMs [1][2][3][4][5][6][7][8][9][10][11], which are based on different assumptions and models and therefore have limited accuracy. In this paper present the new physically motivated precision method for determining V br , which is based on the measurements of the relative SiPM detection efficiency.…”

The avalanche breakdown and Geiger mode of the silicon p-n junction is considered. A precise physically motivated method is proposed for determining the avalanche breakdown voltage of silicon photomultipliers (Si PM). The method is based on measuring the dependence of the relative photon detection efficiency (PDE rel ) on the bias voltage when one type of carriers (electron or hole) is injected into the avalanche multiplication zone of the p-n junction. The injection of electrons or holes from the base region of the Si PM semiconductor structure is performed using short-wave or long-wave light. At a low overvoltage (1-2 V) the detection efficiency is linearly dependent on the bias voltage; therefore, extrapolation to zero PDE rel value determines the Si PM avalanche breakdown voltage with an accuracy within a few millivolts.
