Nanoscale has just published our work on Surface Plasmon Modes of Nanomesh-on-Mirror Nanocavities Prepared by Nanosphere Lithography. Metal-insulator-metal (MIM) structures show great potential for numerous photonic applications due to their ability to confine light energy to volumes with deeply sub-wavelength dimensions. Here, MIM structures comprising hexagonal gold nanohole arrays were prepared by nanosphere lithography. The full details can be found in Nanoscale, 2018, DOI: 10.1039/C8NR05499A
