Raman Staircase in Charge Transfer SERS at the Junction of Fusing Nanospheres.
We present a theoretical analysis of Raman intensities for a molecule that bridges a current carrying junction. Experimental data is used to estimate parameters for the theoretical model. The recently reported staircase of Raman intensities observed during the fusion of nanodumbbell is reproduced.
