High thermal resistivity
WebThe increase in thermal resistivity is significant (a factor of 100) at 150°C, for a relatively low fluence. The low irradiation temperature data for PGA in Fig. 43 do not reach a high enough fluence to saturate. However, at the higher temperatures, data is near saturation.
