With the development of the surface-enhanced Raman scattering (SERS) technique, new multipurpose and multiperformance SERS-active substrates have been developed. Semiconductor and semiconductor/metal composites show versatility and SERS activity for theoretical and practical applications. Semiconductor-based SERS substrates with different microstructures, materials and compositions have been prepared to explore the enhancement effect on Raman signals. The discovery of the SERS enhancement effect of semiconductors makes up for the gap that SERS development is limited to metal-based materials. Semiconductor/metal composite substrates have established preparation technology that is compatible with the characteristics of different materials to form a stable and solid substrate that can regulate the SERS enhancement mechanism. These composites establish a good model for the theoretical research of SERS, which is of great significance to explore its enhancement mechanism. In this review, various semiconductor materials are introduced as SERS-active substrates. Versatile applications of semiconductor-based SERS and its enhancement mechanism are also presented.

基于表面增强拉曼散射的半导体和半导体/金属复合材料的电荷转移研究

随着表面增强拉曼散射 (SERS) 技术的发展，已经开发出新的多用途和多功能 SERS 活性基板。半导体和半导体/金属复合材料在理论和实际应用中显示出多功能性和 SERS 活性。已经制备了具有不同微观结构、材料和成分的基于半导体的 SERS 衬底，以探索对拉曼信号的增强作用。半导体SERS增强效应的发现，弥补了SERS发展仅限于金属基材料的空白。半导体/金属复合基板已经建立了兼容不同材料特性的制备技术，以形成稳定的固体基板，可以调节SERS增强机制。这些复合材料为SERS的理论研究建立了良好的模型，对于探索其增强机制具有重要意义。在这篇综述中，介绍了各种半导体材料作为 SERS 活性衬底。还介绍了基于半导体的 SERS 的多功能应用及其增强机制。
