Abstract

Temperature sensor based on temperature dependence of electric charge carrier traps in the energy band of a solid material, which is subjected to the temperature to be measured. The charge carrier traps are first filled with electrical charges. Thereafter a quantity having a predetermined relation to the emitted charge or to the rest of the charge is measured. The change in the measured quantity has a time constant corresponding to a given temperature. The time constant is indicated and the temperature is calculated.
