Highly perfect n-type CdTe single crystals grown by the sealed-ingot-zone refining method have been used to fabricate semiconductor surface-barrier detectors for X- and low-energy ..gamma..-ray analysis. An energy resolution of 2.0 keV (fwhm) and 1.5 keV (fwhm) was achieved for 59.5 keV ..gamma..-rays from /sup 241/Am and 5.9 keV characteristic K X-ray line from /sup 55/Fe source, respectively. Spectra were measured at room temperature with low detector bias. The observed full energy peak of 59.5 keV ..gamma..-rays has been compared with the theoretical peak calculated for a surface-barrier junction with fixed space charge, the trapping effects being taken into account.
