Plasmon rulers can be used for resolving ultrasmall environmental, dimensional, and material changes owing to their high sensitivity associated with a light-scattering spectral shift in response to changes in the separation between plasmonic nanostructures. Here, we show, in several experimental setups, how cavity plasmons in a metal nanowire-on-mirror setup can be used to probe vertical dimensional changes with sub-picometer differential resolutions using two carefully chosen material systems. ...[more]
