Fig. 3

a False color HAADF images acquired at different times during the 0 V → 5 V → 0 V → −5 V → 0 V sweep in Fig. 2b. Four regions (A1–A4) are defined at the bottom, corresponding to the Pd electrode, the MoS2 channel, the isolated Ag particle, and the Ag electrode, respectively. The red triangles mark the emerging contrast from Ag filaments. b Intensity variation within the four defined areas (ΔA1–ΔA4) as a function of time during the sweep. The corresponding bias voltage is indicated on the top axis. The inset is an enlarged image from the region defined by the dashed rectangle.
