我们已经制作和表征了直径为200 μ m的未钝化圆形梅萨Al（0.8）Ga（0.2）As p（+）-i-n（+）二极管作为软X射线光子计数探测器。光谱性能，从（55）Fe放射性同位素的5.9 keV的X射线线的半高宽测量，表明这些探测器可用于X射线光子计数光谱与有前途的能量分辨率（0.9-2.5 keV）在-30至+90摄氏度的温度范围。(C)2010 Elsevier B. V.保留所有权利。
We have fabricated and characterised unpassivated 200 mu m diameter circular mesa Al(0.8)Ga(0.2)As 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 (55)Fe 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 degrees C temperature range.
