a Monolayer MoS2 on CA·M molecular film device for HER measurements. The red arrow indicates the charge transfer direction in the heterostructure. b Raman spectra of the monolayer MoS2 flake on CA·M before (black) and after (red) HER measurements, and Raman peak positions are marked by the dashed lines. c The polarization curves for HER on Platinum (dashed blue line) and monolayer MoS2 flakes under different conditions (SiO2 substrate with/without 2D CA·M buffer layer, and the respective voltages applied gate). The −10 mA cm−2 current density position is marked by the dashed red line. d Corresponding Tafel curves.
