摘要
The authors have fabricated the thin-film transistor (TFT) with CdSe and CdS semiconductor thin films, prepared by a low temperature chemical bath deposition (CBD) method, as an active layer. The ON-current values of the CdSe-TFTs and CdS-TFTs at a gate bias of 10 V and a source-drain voltage of 10 V are about 100 MA and 5 pA, respectively. The OFF-current values of the CdSe-TFTs and CdS-TFTs at the source-drain voltage of 10 V are less than 10 pA. The fabricated CdSe-TFTs exhibited a field effect mobility of 15 cm(2)/V-s, threshold voltage of 3.5 V, subthreshold slope of 0.5 V/dec., and ON/OFF current ratios exceed 10(7). A field effect mobility of 1 cm2/V-s, a threshold voltage of 2.6 V, a subthreshold slope of 0.6 V/dec., and an ON/OFF current ratios exceed 10(6) were observed for CdS TFTs.
