Abstract
In this research, a multilayer transparent conductive electrode was designed and optimized using a D/M/D/M/D multilayer nanostructure on a glass substrate. The main purpose of this design was to improve the optical transmission properties and electrical resistance. The optimal material and thickness of each layer were determined using Essential Macleod software. The electrical and optical properties of the multilayer nanostructure were then investigated, including surface electrical resistance, optical transmittance, and reflectance. The results showed that the best structure was TiO2/Ag/ZnS/Ag/TiO2, with silver layers of 10 nm thickness, ZnS layers of 30 nm thickness, and TiO2 layers of 20 nm thickness. Under these conditions, the coefficient of merit FTC=0.11026 Ω was obtained, indicating the highest efficiency of the structure. The surface electrical resistance was approximately 5.624Ω/sq, and the optical transmittance in the visible region was 94.65%. These values demonstrate that this structure is suitable for use as a transparent conductive electrode in optoelectronic applications. Therefore, the TiO2/Ag/ZnS/Ag/TiO2 structure can serve as a suitable substrate in nanoelectronic and optoelectronic technologies. The article focuses on the 5-layer electrode with mirror symmetry based on D/M/D/M/D layers, exploring the influence of various factors such as layer materials, thickness, and arrangement, and optimizing the structure to achieve the highest transparency and conductivity.
