Temperature dependence of AlGaAs soft X-ray detectors
journal contribution
posted on 2023-06-08, 16:18 authored by Anna BarnettAnna Barnett, D J Bassford, J E Lees, J S Ng, C H Tan, J P R DavidWe have fabricated and characterised unpassivated 200 µm diameter circular mesa Al0.8Ga0.2As p+–i–n+ diodes as soft X-ray photon counting detectors. The spectroscopic performance, as measured by the FWHM of the 5.9 keV X-ray line from an 55Fe radioisotope, shows that these detectors can be used for X-ray photon counting spectroscopy with promising energy resolution (0.9–2.5 keV) over a -30 to +90 °C temperature range.
