我们描述了肖特基碲化镉二极管探测器用于光谱分析的最新进展。CdTe二极管的低漏电流使我们能够施加比以前的CdTe探测器更高的偏置电压。对于0.5-1 mm厚的相对薄的检测器,高偏置电压导致器件中的高电场。改进的电荷收集效率和低漏电流导致在60 keV下对于2/spl times/2 mm/sup 2/器件的能量分辨率优于600 eV FWHM,而无需任何电荷损失校正电子器件。现已推出尺寸为21/spl times/21 mm/sup 2/的大面积探测器,能量分辨率为/spl sim/2.8 keV。对于相对薄(< 1 mm)的探测器,如果它们被冷却或在高偏置电压下工作,则可以容易地获得长期稳定性。
We describe recent progress on the use of Schottky CdTe diode detectors for spectrometry. The low leakage current of the CdTe diode allows us to apply a much higher bias voltage than was possible with previous CdTe detectors. For a relatively thin detector of 0.5-1 mm thick, the high bias voltage results in a high electric field in the device. Both the improved charge collection efficiency and the low-leakage current lead to an energy resolution of better than 600 eV FWHM at 60 keV for a 2/spl times/2 mm/sup 2/ device without any charge-loss correction electronics. Large area detectors with dimensions of 21/spl times/21 mm/sup 2/ are now available with an energy resolution of /spl sim/2.8 keV. Long term stability can be easily attained for relatively thin (< 1 mm) detectors, if they are cooled or operated under a high bias voltage.
