Fig. 6.

(a) Calibration curve for an electrical response of the SbSeI nanogenerator and (b) open-circuit voltage response of the SbSeI nanogenerator to ultrasound excitation emitted by a Sonic-6 reactor (Polsonic). Black points represent the experimental values. Solid red curves in (a) and (b) show the best fitted dependences described by Equations (6), (1), respectively.
