WebThe dark count can be obtained by integrating the rate of carrier generation between (w 2 –w 1) and w 1. As a result, the dark count generated by these three effects can be estimated by using the following equation: where P tr (x) is the probability of carrier avalanche triggered at position x in the depletion region and is expressed below. WebJul 1, 2015 · From Fig. 3 one can conclude that the effective dark count rate is reduced 10× by lowering the temperature by 30 K. Operating the 200 µm diameter detection chip at a room temperature, gating it at the rate of 10 Hz and biasing it 2.5 V above its breakdown voltage its effective dark count rate is typically several MHz.
