Temperature dependence of AlGaAs soft X-ray detectors

We have fabricated and characterised unpassivated 200 μm diameter circular mesa Al 0.8Ga 0.2As 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...
