Abstract

In recent years, there has been a growing demand for efficient and sustainable devices. This has led to an increased interest in novel materials with enhanced optoelectronic properties. Silicon nanowires (Si NWs) and graphene are two promising candidates for these applications due to their exceptional electrical, mechanical, and optical properties
This paper succeeded in fabricating and characterizing hybrid nanostructures of SiO NWs/graphene and ZnO NPs using pulsed laser deposition (PLD)and by different numbers of pulses (200p,300p,400p,500p). where Characterization of the crystallographic, morphological, and optical properties such as XRD, FE-SEM , AFM and Diffuse reflectance for the synthesized hybrid nanosystems revealed that the addition of graphene and ZnO nanoparticles led to increased roughness values and changes in the surface topography of the membranes.
In the research, high-purity materials were used to ensure reliable and accurate results. The silicon wafer used was a p-type model with a crystal orientation of 110, and a purity of 99.99%. The wafer was purchased from a reputable company Henan CXH Purity-China, with a standard-GB specification. Nitric acid was used in the research, and its concentration was 65.9%
