Insight into the Heterogeneity of Longitudinal Plasmonic Field in a Nanocavity Using an Intercalated Two-Dimensional Atomic Crystal Probe with a ∼7 Å Resolution.
Siyu Chen,Shirui Weng,Yuan-Hui Xiao,Pan Li,Miao Qin,Guoliang Zhou,Ronglu Dong,Liangbao Yang,De Yin Wu,Zhongjun Tian +9 more
TL;DR: In this paper , a two-dimensional atomic crystal was used as a spacer layer to overcome the randomness of the molecular adsorption and Raman vibration direction, and it was shown that the longitudinal plasmonic field in an individual nanocavity is heterogeneously distributed with an unexpectedly large intensity gradient.
