Annotation

This study provides insights into the phenomenon of surface photoemission from metal nanoparticles, considering the excitation of Localized Plasma Resonance (LPR). LPR induces significant changes in electron density and electric field, resulting in enhanced photoemission compared to macroscopic structures. Theoretical formulations, including expressions for photoemission probability, are elucidated, enabling a deeper understanding of the process. Practical implications are discussed, emphasizing the development of optoelectronic devices and efficient photodetectors using nanoparticles. Results demonstrate the spectral dependence of photoemission probability and current, high-lighting the suitability of materials like copper for nanoparticle-based applications. The study con-tributes to optimizing nanoplasmonics effects and expands the material choices for efficient photoemission.
