Fig. 5: Comparison of the Schottky superlubric generator (S-SLG) with reported Schottky generators (S-Gs)3,14,15,17,18,19,20,22,24,25,39.
From: Microscale Schottky superlubric generator with high direct-current density and ultralong life
a Current density J and lifetime T of S-Gs and S-SLG, where different shapes and colours of dots represent different types of S-G, and black and red dotted lines indicate the power exponential fitting of all points and three upper right points of reported S-Gs, respectively. b Transfer charge density q, which is the integral of the current density over time (\(q = {\int}_0^T {Jdt}\)), of S-Gs and S-SLG, where different colours represent different types of S-G.
