(a) Experimental results of the dI/dV for the NbSe2 surface (2 H CDW phase) with the power of RF (1 GHz) at the tunneling junction (indicated as VAC on the right side of each plot. (b) Simulated dI/dV based on Eq. (1), whose eVAC parameters are indicated as VAC for each plot. (c) Variation of the energy position of the dominant peaks of (b). For each VAC, the energy positions of the majority peak are indicated by a small square. The linear line is the fitting result of the least-square method.
