Changes

* The average rate at which a valence band electron scatters by hitting a defect or a phonon in the silicon crystal

* The average rate at which a valence band electron scatters by hitting a defect or a phonon in the silicon crystal

* The number of valence electrons in the active region

* The number of valence electrons in the active region of the detector

The dark rate is calculated by multiplying these three factors together. It is the probability of an event, multiplied by the rate at which the probability is calculated, then multiplied by number of places that this is occurring simultaneously.  

The dark rate is calculated by multiplying these three factors together. It is the probability of an state, multiplied by the rate at which electrons can enter that state, then multiplied by number of electrons that are participating simultaneously.
