description: The subject of the graduate qualification work is Â«Study and simulation of silicon nanowires decorated with silver nanoparticlesÂ». As a result of the work done, a computer model was created in Comsol Multiphysics for SiNWs decorated with silver nanoparticles, and the components of this model were studied. The factors influencing the LSPR, as well as the degree of their influence, were identified. The strongest factor influencing the position of the LSPR is the dielectric environment. For particles with a radius of 10 nm in air an LSPR is obtained at a wavelength of approximately 360 nm, on silicon a resonance is at a wavelength of approximately 600 nm. Also, the position of the LSPR is less affected by the particle size and interaction with other particles. The second effect depends on the distance between the particles and the orientation of the electric field. Strengthening the field near nanoparticles by more than 100 times can also be obtained by creating clusters of nanoparticles and a dielectric environment. The results of this work can be applied in the analysis of the experimental spectra of SiNWs decorated with metal nanoparticles, as well as in predicting the properties of these structures.
