a Effect of ∆T on charge transfer and dissipation. The black dots represent the electrons, and the black lines represent different energy levels. The brown, blue, and red curve represent the potential wells of different friction layers, respectively. b Numerical simulations of the relationship between ∆T and the short-circuit transfer charge density. The relationship between the temperature of the hotter friction layer (Th) and the temperature of the cooler friction layer (Tc) is shown in the inset. c The potential distribution of TENG under different ∆T. d The influence of the thermal conductivity of the cooler friction layer on Tc. e The influence of the thermal conductivity of the cooler friction layer on the surface charge density of the cooler friction layer.
