Dark Rate = X events/second
Dark Rate = Probability of occurance * Volume of Sensitive area * Rate of redistribution of energy (collisions)
P r o b a b i l i t y = e − E g / k T {\displaystyle Probability=e^{-E_{g}/kT}}
E g S i l i c o n = 1.12 e V {\displaystyle E_{g}Silicon=1.12eV}
k = 1.3806503 ∗ 10 − 23 J K − 1 {\displaystyle k=1.3806503*10^{-23}JK^{-1}}
P r o b a b i l i t y = e − 1.12 / ( 1.381 ∗ 10 − 23 ∗ t ) {\displaystyle Probability=e^{-1.12/(1.381*10^{-23}*t)}}
thin depletion region (0.7-0.8 um)
V o l u m e = 4.4 m m 2 ∗ 0.075 m m {\displaystyle Volume=4.4mm^{2}*0.075mm}
V o l u m e = 0.33 m m 3 {\displaystyle Volume=0.33mm^{3}}
