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.
