We investigated structural control of dielectric nanospheres partially coated with metal (semi-shell structures) by treating the sputtering current as a key parameter. Experiments using Ag thin films revealed that the sputtering current affects thermal stability, morphology, and surface plasmon resonance characteristics, indicating its effectiveness in tailoring diverse optical responses.
