We have studied the effect of sulfur treatment on the performance of a CdTe radiation detector with an Al Schottky electrode. After sulfur treatment, the leakage current was $1.51 \times 10^{-9}$ A at a bias voltage of 250 V, whereas that of a sample without sulfur treatment was $7.90 \times 10^{-9}$ A. Moreover, samples with sulfur treatment were capable of measuring the $\gamma$-radiation from 241Am for 150 min, while samples without sulfur treatment were incapable of measuring the $\gamma$-radiation after 30 min. The improvement in the polarization of the CdTe radiation detector was achieved by the sulfur treatment of the CdTe surface.
