The effects of different laser parameters were extensively studied through optical, structural, and morphological properties. The optimal conditions were selected and analyzed after each preparation process. The optimal sample was used to prepare the heterogeneous junction Au@Nb2O5/P-Si and characterized as a function of the active layer thickness.
After studying the effect of each laser parameter on the preparation of Au@Nb2O5 nanoparticles, the optimal conditions were chosen and utilized to manufacture the heterogeneous photodetector device Au@Nb2O5/P-Si with varying active layer thickness. The results also showed that the photocurrent is directly proportional to the incident light intensity, indicating the possibility of the junction functioning as an effective photodetector.
