Abstract :
In this paper the influence of temperature fluctuations on the response of thick gate oxide metal oxide semiconductor dosimeters is reviewed and the zero temperature coefficient (ZTC) method is evaluated for error compensation. The response of the ZTC current to irradiation is studied showing that the error compensation impoverishes with absorbed dose. Finally, an explanation and analytic expression for the shifts in the ZTC current with irradiation based on the interface traps creation is proposed and verified with experimental data.
