Аннотация: <jats:p>The work proposes a model for analyzing oscillations of charge carriers in systems consisting of a single metal nanoparticle located on a graphene monolayer and excited by an electromagnetic pulse directed normally to the graphene surface. Unlike previous studies where graphene served only as a conductive medium for charge Показать полностьюtransfer between metal nanoparticles, here we focus on the direct interaction between a metal nanoparticle and graphene. This includes studying nanoparticle–graphene charge transfer dynamics and carrier distribution in graphene. For systems containing nanoparticles of different radii, it is shown that the real part of the frequency of the graphene charge density fluctuations is approximately 6.5×1014 Hz, while the imaginary part of the frequency dominates the real part. Graphene interband conductivity is also shown to be critical.</jats:p>
