The average energy consumed in the generation of an electron-hole pair (epsilon(ALInP)) in Al0.52In0.48P was experimentally measured across the temperature range -20 degrees C to 100 degrees C, using a custom AlInP X-ray-photodiode, an Fe-55 radioisotope X-ray source, and custom low-noise charge-sensitive preamplifier electronics. epsilon(ALInP) was found to linearly decrease with increasing temperature according to the equation epsilon(ALInP) =(-0.0033 eV/K +/- 0.0003 eV/K) T + (6.31 eV +/- 0.10 eV). At room temperature (20 degrees C), epsilon(ALInP) = 5.34 eV +/- 0.07 eV.
