Abstract

Cadmium sulfide (CdS), an II-VI group semiconductor material, is one of the most investigated semiconductors in thin film form. In this work, we synthesized CdS thin films with improved film morphology in the presence of ethylene diamine (EA) as the complexing agent by chemical bath deposition (CD) at lower pH. Detailed characterization reveals the presence of cubic phase CdS with a band gap of 2.39 eV with the resultant morphology significantly influenced by the composition of the growth solution. The resultant CdS films finds prospective application as a humidity sensor with a high sensor response of 2.61 corresponding to 80% relative humidity.

在低pH下化学浴沉积具有改善形态的硫化镉(CdS)薄膜用于湿度传感。

硫化镉(cd)是一种II-VI族半导体材料，是薄膜形式研究最多的半导体材料之一。在本研究中，我们以乙二胺(EA)为络合剂，在较低ph下通过化学浴沉积(CD)合成了具有改善薄膜形貌的CdS薄膜。详细表征表明，存在带隙为2.39 eV的立方相CdS，其形貌受生长溶液组成的显著影响。所得的CdS薄膜在相对湿度为80%时具有2.61的高传感器响应，有望应用于湿度传感器。
