Abstract Previously, an Al 0.52 In 0.48 P p+-in+ spectroscopic photon counting X-ray photodiode with 2 μ m thick i layer (200 μ m diameter) was shown to suffer from energy-dependent incomplete charge collection noise (Lioliou et al., 2019). Subsequent measurements on a larger (400 μ m diameter) Al 0.52 In 0.48 P p+-in+ photodiode (reported here) revealed the presence of even greater incomplete charge collection noise. Given these findings, an expectation would have been that thicker Al 0.52 In 0.48 P structures (which would be required for efficient absorption of all but the softest X-rays) would have a greater incomplete charge collection noise contribution, thus suggesting that thick Al 0.52 In 0.48 P photodiodes may be of limited practicality as high performance detectors for photon counting X-ray spectroscopy. However, two new Al 0.52 In 0.48 P p+-in+ photodiodes (with 6 μ m i layers) were fabricated from material grown by the same technique (metalorganic vapour phase epitaxy) in the same reactor, and are now shown here to exhibit no signs of detectable incomplete charge collection noise under the illumination of X-ray photons of energy 4.95 keV to 21.17 keV. As such, now that greater experience has been built with Al 0.52 In 0.48 P, concerns about incomplete charge collection noise in X-ray detectors made from the material appear to have been unwarranted; the path towards thick Al 0.52 In 0.48 P X-ray detectors is now clear.
