Abstract

In this work we perform direct nano-imaging of nanostructured Bi1.5Sb0.5Te1.8Se1.2 (BSTS) topological insulator in the visible range and show the evidence of dipolar and higher order local surface plasmon modes. Revealed plasmon modes in BSTS nanostructures present the TI as a good plasmonic material beyond noble metals.
