Total Ionizing Dose and incoming particle frequency

A few months ago, after presenting my first year PhD results at the University of Southampton, I was asked “Are your results affected by the frequency of the incoming particle?” and the answer is very simply no. But here is a more detailed analysis of the physics involved one step before Total Ionizing Dose (TID) mechanisms for a gamma ray source – which is what we are using.

As is generally known, Total Ionizing Dose creates electron-hole pairs, and this is what device physics studies. The electron-hole pair generation rate is given through the following relationship,
