英文摘要 | 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. Specifically, we monitor the dielectric layer thickness changes in response to growth using atomic-layer deposition and to thermal expansion, demonstrating a sensitivity of 14-nm spectral shift per Angstrom thickness change and 0.58 pm of vertical differential resolution, respectively. The findings confirm theoretical predictions and highlight the potential use of cavity plasmons in some ultrasensitive sensing applications. |
