Abstract
We study magnetic and electric hotspots in the gaps of nanoparticle dimers and trimers composed of hollow silicon nanoparticles. We find that the hollow size markedly influences the overall shape of the field enhancement, in particular, the peak magnitude and the peak position. The peak shifts about 100–200 nm as the hollow size varies. Tuned magnetic hotspots allow one to better enhance the Raman optical activity and circular dichroism of molecules, the interaction of light and nanomagnets, and so on.
