HIGHLIGHTS
- What: The research on plasmonic dimers mainly focuses on metallic nanoparticles made of gold, silver, and copper, where SHG is forbidden in the bulk because of the microscopically centrosymmetric arrangement of their atoms. The authors focus on individual nanosphere dimers rather than regular arrays, thereby eliminating any potential influence arising from collective effects, such as plasmonic surface lattice resonance (SLR) and other analogous phenomena . The authors demonstrate modulation of the SHG intensity in gold nanosphere dimers through symmetry breaking.
- Who: Dangyuan Lei from the (UNIVERSITY) have published the research work: Symmetry-breaking-induced off-resonance . . .
