It was found that there is a point of inflexion, T0, on the temperature dependence of the voltage response of the detector. The voltage response increases with temperature for temperature of the detector T<T0, and decreases with temperature for T>T0. Two time scales are found to be due to the two thermally resistive bonding layers. The inflection temperature is determined by the impurity concentration. For temperature T<T0, the temperature dependence of the voltage response depends on the variation of mobility of the carrier , whereas T>T0, thermally generated carriers contribute to the voltage response. %K band-off laser %K photoconductive detector %K thermally generated carriers %K mobility
