Abstract
The photoconductivity of CdS single crystals was measured by using the acoustic surface wave. At 130 K, we observed the peaks at 474, 486, 494 (P1), and 505 (P3) μm. The peaks at 474 and 486 μm are due to the exciton transition. P1 and P3 are due to the sulphur vacancy. The temperature shift of the band edge is estimated to be −3.7×10−4 eV/deg from P1 and −3.5×10−4 eV/deg from P3.Keywords
