… To overcome this challenge, we proposed an enhanced plasmonic sensing technique
through the phase singularity-related Goos-Hänchen (GH) interrogation method with an
enhanced zero-reflection performance by the atomically thin phase change nanomaterials [2-4].
We constructed an optimized multi-layered metallic sensing substrate based on GST and gold
thin film. Experimental results show that the sensitivity in Goos-Hänchen (GH) shift has been
greatly enhanced compared to pure gold substrate by more … These atomically thin phase …
We designed an enhanced plasmonic sensing device based on 2D Ge 2 Sb 2 Te 5 phase change nanomaterials. The sensing capability has been experimentally demonstrated to be 7000, 000 μm/RIU with a detection limit of 10 fM for BSA molecules.
