Abstract: The temperature dependence of the average energy consumed in the creation of an electron-hole pair in the wide bandgap compound semiconductor Al[subscript 0.8]Ga[subscript 0.2]As is reported following X-ray measurements made using an Al[subscript 0.8]Ga[subscript 0.2]As photodiode diode coupled to a low-noise charge-sensitive preamplifier operating in spectroscopic photon counting mode. The temperature dependence is reported over the range of 261 K–342K and is found to be best represented by the equation ε[subscript AlGaAs]=7.327–0.0077 T, where ε[subscript AlGaAs] is the average electron-hole pair creation energy in eV and T is the temperature in K.
