Abstract: We present measurements about the thermal parameters of our TeO 2 bolometric detectors, operated in the Gran Sasso Laboratory to search for rare events. These measurements allow us to model the detectors. We have introduced a parameter, detector figure of merit, that allows to compare the device performance.
